Introduction
PRODUCT OVERVIEW
The 332 radar has taken the powerful feature rich experience from the low power AGD331. Using the latest power
saving technology, the radar’s design is a unique pulsed, frequency modulated transceiver linked to a 32bit ARM
Cortex M4 processor. This helps deliver market leading radar performance while maintaining extremely low
power usage.
Traditional Continuous Wave (CW) Doppler radars for sign driving applications have no ranging capability.
The 332 contains filter-down technology from AGD enforcement products, this furnishes the radar with a full
multi-target acquisition platform, accurate range measurement, and adjustable output rate of targets. To the
VAS designer, this simply means the system power is more eiciently managed by the ability to select the area of
interest accurately (regardless of vehicle size).
Designed to be simple to use and quickly deployed with a variable sign solution, the 332 range and low speed
can be set-up via an RS232 serial interface.

Installation
PHYSICAL INSTALLATION
The radar should be mounted on a firm structure at the recommended mounting height of 2m to 5m. For
optimum performance the radar should be situated on a pole adjacent to the carriageway with an unobstructed
view of the advancing traic. The radar should point down the road towards the furthest point of detection.
The front face of the radar should be vertical i.e. perpendicular to the road before you begin site specific
adjustments.
The relatively wide beam profile of the 332 ensures good detection coverage of single or dual lane approaches
with relatively little adjustment of the sign in relation to the direction of approaching targets.
The recommended mounting height of the radar within the sign is between 2-5 meters with the optimum
being 3 metres.
The radars front face should be 90
0
to the road surface, inclines in the road surface should be catered for by
adjusting the 332 radars mounting angle.

PHYSICAL INSTALLATION
The 332 is a true range measuring radar that allows the user to select the range that target starts reporting on
tracked targets.
Each target needs to return suicient signal in order for the radar to track its range. A target return amplitude is
related to its Radar Cross Section (RCS) which is in part related to the reflecting area of the target. Targets that
have a larger RCS will return a larger signal than those with a smaller RCS.
For example: If the detection range is set at 80 metres then all targets that return enough reflective power before
this point will be tracked. Only when the target reaches 80 metres will the detection be reported, allowing for
accurate actuation of the sign at the correct range.

Radar Commands and Configuration
RADAR COMMAND OVERVIEW
Commands can be used to control the operation of radar. These are sent over the RS232 UART Link.
Commands are immediately followed by an operator that indicates the required action. Not all the operators
are supported for all commands. Where an operator is used and it is not supported the radar will respond with
warning message. The table shows the commands used by the radar.
Operator Operation
= Set a parameter to a value e.g. *LS=50<CR>
? Respond with value or values
^ Set default value for parameter
$ Provide help on the command
! Do something e.g. *REBOOT! Reboots the radar
Command Operators
Where a command is used to enquire or set a radar parameter the radar will respond in a set way. The radar
will respond with a hash, #, followed by the command name, operator used and then the value of parameter or
parameters.
For example
*DIR=A<CR> Radar responds with #DIR=A<CR>
*DIR?<CR> Radar responds with #DIR?A<CR>
Communication Tasks
The operation of the 332 radar has been optimised as a low power device with minimal processing overhead.
It is good practice to not ‘overrun’ the communication line with repeated send commands when the radar is
operational.
Command requests to store settings are written to EEPROM each time they are sent from the host system,
repeated sending of commands will erode the lifetime capacity of the radars non-volatile memory.

Radar Commands and Configuration
RS232 OUTPUT MESSAGE
The speed of a single target of interest can be reported using the RS232 connection. This is typically used to
display the actual speed of a target as it approaches the sign.
The *OUT3 command allows the user to filter which target to report by it’s speed, range and direction.
In the case of multiple valid targets at any one time, the *MM command allows the user to decide which target to
report:
*MM=2 (default, recommended)
report the valid target that’s been tracked for the longest period of time.
e.g. a valid target travelling at 32kph will be reported even if a new 50kph target is seen
3 seconds later.
*MM=3
Report a smoothed speed of the target thats been tracked for the longest period of time.
e.g. a valid target travelling around 32kph (±2kph) will have its average speed reported over the
duration it’s been tracked, even if a new 50kph target is seen 3 seconds later.
*MM=1 (not recommended)
report the valid target with the fastest speed, regardless of distance from the sign or duration of the
track.
e.g. a valid target travelling at 32kph will no longer be reported when a new 50kph target is
seen 3 seconds later.
The *MS command controls the format of a reported message & the rate at which they are sent.

Radar Commands and Configuration
RADAR COUNT OUTPUT
The count functionality of the radar is available in two formats. It can be presented as a digital pulse on *OUT2
only (it cannot be configured to be output on *OUT1), and it can be viewed / read from the RS232 data string
*OUT3.
Configuration using RS232
The count function can be activated using the *OUT2=COUNT command (detailed in the ‘Radar Command List’)
With the ‘Count’ set, it is then possible to set the radar to count advancing, receding or bi-directional targets.
These are distinguished on the FET 2 digital output by the length of pulse and in the RS232 string with either a
*C,A<CR> for an advancing target, or *C,R<CR> for a receding target.
Vehicle Count Principle of Operation
The range at which vehicles are counted in both advancing and receding directions has been carefully tested
and calibrated and is a non adjustable value. The distance for advancing is 20 metres and the distance for
receeding is 40 metres.
FET 2 Digital Output
FET 2 in count mode will only pulse ‘ON’ once per frame to represent a vehicle count, the length of the pulse
allows the data to be extracted from the FET 2 output:
35ms ‘Pulse’ = 1 advancing target counted this frame
55ms ‘Pulse’ = 1 receding target counted this frame
75ms ‘Pulse’ = 1 advancing AND 1 receding target counted this frame
Count Accuracy
Free flow, moderate and heavy flow studies have returned an average accuracy of >93%. When the radar is
operating in OM=LS mode looking at slow moving traic, the accuracy will be reduced depending upon variables
such as gaps between vehicles.

Radar Commands and Configuration
DYNAMIC FRAME RATE (PATENT PENDING)
Dynamic frame rate is used to reduce the power consumption of the 332 whilst no valid targets are being
detected. It does this by reducing the number of times the transmitter looks for a target per second, aer the 332
has not detected a target for 1 second. You can set the dynamic frame rate anywhere from 0 to 20 with a default
value set at 2 by entering the *DFR command. Once a target is detected the transmitter will start operating at its
standard rate (10Hz) and will continue to do so until the 332 does not detect a valid target for 1 second.
The dynamic frame rate entered could impact the distance at which a target is seen, the higher the dynamic
frame rate the longer it could take to spot another potential target. See table below
FIRMWARE UPDATE
The 332 radar is designed to be re-flashable with firmware updates. Please contact AGD technical support for
further instruction.

TROUBLESHOOTING
The radar has an update/frame rate of 10Hz (ie a response time of 100ms), can we not decrease the update
rate and save more power?
Yes, more power can be saved but the radar has been optimised for use on both urban and high-speed
roads. A vehicle travelling at 130kph (80mph) will produce a detection distance latency of about 4m at 10Hz
which is of the order of the user range setting intervals. However, the 332 does have a feature to decease the
frame rate (*DFR command). Dynamic frame rate reduces the power consumption of the 332 whilst no valid
targets are being detected. It does this by reducing the frequency that the transmitter looks for targets when
the 332 has not detected a valid target for longer than 1 second (see page 15).
What is the advantage of an FMCW radar over normal sign activation radars that are based on speed
detection by simple Doppler only?
An FMCW radar is a much more complicated radar architecture that allows the speed and the range of the
target to be measured. This ensures that the sign is always activated at the same target distance. It is one
of the main drawbacks with traditional low cost radars that you may have the sign activating at 140m for a
truck and only 60m for a small car. Additionally, the set activation distance is almost completely unaected
by rain and fog etc with an FMCW radar compared to a traditional Doppler radar.**
**There are some additional explanatory notes on performance invariance owing to weather.
The radar I currently use sometimes has a large delay in detection of an approaching vehicle and hence
sign-activation when a large target is receding in the adjacent carriageway. Is this improved with the 332?
The 332 radar processes many targets simultaneously so the detection distance for the oncoming vehicle
can be detected even when there are large receding targets.
Why is the ability to set a reliable sign activation distance so important?
If the detection distance is too short the driver has no response time to absorb the sign’s message. If the
detection distance is too large the sign is illuminated for a longer duration and hence more power is used
which can be critical in low power applications. You need the sign to be on for just the right duration and at
the right distance for the value of the sign message to be delivered to the driver. This distance will vary with
the site and with the sign message.
Why is the LED on the 332 flashing repeatedly or intermittently?
The operational voltage supply range for the radar is 5.5 to 15Vdc (nominal 12Vdc). It is possible, especially
in solar & battery based installations that the voltage supply level can fall outside the specified limits.
Operation of the radar is not guaranteed outside these limits and incorrect operation can be manifest in an
erratic or flashing LED state. Please check the voltage supply and reconnect the radar.

TROUBLESHOOTING
The 332 radar can be re-flashed. What does this mean?
There is a development plan to include new features in the radar going forward. Customers who use a current
version of 332 will not be disadvantaged by not having access to these new features. Re-flashing means we can email
new application code that can be uploaded into the 332 radar over the RS 232 link which will enable new functions
as they are available. There is no requirement for the customer to return the hardware to AGD for upgrade.
The sign has been EMC tested and the radar has a CE mark. If I put the radar on the sign will that be
enough to legally put this on the market in the EU?
This is not a safe assumption to make. There are special directives and associated specifications in the EU
regarding radio devices (radar is classed as a radio device) and care should be taken on building a file for
conformity. AGD has good experience on this and can give guidance or your usual Notified Body will give you
independent advice on your required test documentation, Declaration of Conformity and product labelling etc.
The accuracy of the speed measurement appears very good in the documentation is this likely to be the
same for real targets?
The real world is a complex place and there are several known eects that can aect the speed accuracy. For a
single target at 50m travelling directly towards the radar with a speed of 60kph will return a speed reading from the
radar of 60kph ±3 with close to 100% confidence level. If the vehicle is quite close to the radar such that it is starting
to ‘pass’ the sign, the vehicle is no longer travelling directly towards the radar and an angle is formed between
the direction of travel of the target and the boresight of the radar. In this case the speed of the target is eectively
reduced at the radar by the cosine of this angle. Additionally, if the radar is used on a dual carriageway two vehicles
in the adjacent lanes at similar distances travelling at a speed dierence <8kph will have their speeds merged by
the radar. In this specific case, the speed output of the radar will be between the two vehicle speeds.
The radar has a high speed measurement specification of 160kph (99mph). What happens for targets
travelling above this speed?
For targets travelling above the upper speed threshold limit there will be no output from the radar in normal
operation. The radar will ‘see’ the target but not in a meaningful way that will allow the radar to make an output.
If we need the radar to output for targets over 160kph (100mph) is there anything that can be done?
The radar has been optimised for low power and as a result the speed processing task has been restricted to
keep the processing overhead low. The upper threshold for speed could be increased but at the expense of
current consumption. This change is not a simple internal radar setting and would require a revision to the radar
operational firmware.
How accurate is the speed measurement?
The speed measurement algorithm in the 332 radar is a cut-down version of the speed measurement algorithm
used in high grade speed enforcement radars manufactured by AGD. The 332 radar outputs the speed of the target
to the nearest integer. It is rounded to the nearest integer from a calculation of more significant figures. Each
radar is calibrated with a tolerance of +/-3kph using AGD’s traceable calibration equipment. Calibration results are
available upon request for each serial numbered radar.
The target range measurement is treated in the same way as the speed measurement.
