Chapter 1 Product overview
1. Product introduction
The panel microwave speed measurement radar is implemented on Doppler principle, and
it is also called Doppler radar. The working principle is that the radar emits a fixed frequency
microwave signal towards a target and then receives the reflected signal. There will be a
frequency difference between the emission beam and the echo, which is called Doppler
frequency shift. We can calculate the speed of the target through the specific relationship
between this frequency shift and the speed.

a. Install the cardan
Before installing the radar, we need to install cardon first.
Cardon is one of the most common methods to install the radar of CSR-I series and it is
able to be installed in the different environmental conditions after adjusting appropriately.
The installation method of cardon is very simple, and please refer to figure 2.4. The design
sketch after installation can be referred to figure 2.5.
Figure 2.4 Figure 2.5
Attention: The installation direction of radar has a very vital influence upon the speed measured.
Please confirm the validity of installation direction when installing the radar and install it according to
the direction shown in figure 2.6.

-6-
Figure 2.6
b. Adjust the installation position of radar
For the top loading mode, install the radar right above the lane and the detection direction of the radar is
towards the middle of the lane as shown in the figure 2.7. For other methods, put the radar towards the
position expected.
Figure 2.7 Figure 2.8
c. Adjust the angle of pitch
The angle of pitch of radar installation is also called installation angle as shown in the figure 2.8.
Attention: The installation angle θrefers to the included angle between radar plane
and vertical plane instead of horizontal planes.
Please adjust the angle of pitch of radar to the scheduled installation angle, referring to the
recommended installation parameters of all kinds of radar in the table 2.1.

Refer to “Radar electrical interface” and connect the power line and communication line.
Attention: The power supply can be only electrified after finishing connecting all the cable
and checking without error.
3. The debugging and usage of software
a. Software introduction
The radar of CSR-I series are all allocated with the debugging software TSRadar2.01. Not
only can it set the all the kinds of parameters of the radar in detail, but also control the working
conditions of radar very easily.
TSRadar2.01 debugging software is developed based on Windows operation system so that it is able to
run in the main current Windows operation system including Window 7、Windows XP and so on.
This instruction book takes an example of Windows XP to explain the debugging and usage of
TSRadar2.01 in details.
b. Usage of the debugging software
1). The surface of the software
It’s divided into “the communication setting area(1)”, “The current speed display area
(2)”, “the main display area(3)”, “the auxiliary display area(4)”. As shown in the figure 2.10:

2). Serial port
Please confirm the connection between radar and the host computer is correct and select
the correct serial port first on the surface of TSRadar2.01. As shown in the figure 2.11:
Figure 2.11
Attention: If the connection port is chosen incorrectly, the debugging software cannot
receive any information.
If cannot find the port number, please follow the steps as below:
First, open the control panel, find the “System”button, and click the “device manger”button in the
hardware options. Then find the “COM&LPT”and the port number shown in it is just the radar port number.
3). Radar electrification
Monitor the moment of the radar electrification and confirm if there is power-on identification:
0xFE, 0xFD, 0xFD, 0xFE in the communication area. The radar is in the speed measurement state
and can detect the target if the above string is displayed normally.
4). Parameters setup
If needed click the button of “Enter the setup”. As Shown in the figure 2.13, in the status of
setup, the relevant parameters can be adjusted in the communication area:

Figure 2.13
For instance: if the mode of “contact terminal” is needed, click the button of “Enter the setup”
first and then choose the contact terminal, and then, click the “work mode” to confirm. Click the
“Quit the setup” in the final.
4) Mutual information
“ The main display area(3)” will provide the information of radar, communication results,
debug parameters and so on, in hexadecimal format.
5) Speed display
“The current speed display area (2)” will provide the current speed value. Please select the
“locked” button to display in advance.
Attention: Before using, you need to choose in the data formatting options on the right, which is the
auxiliary display area(4). Please ensure that it has no difference from the data formatting of the radar so
that it can show the correct speed.
6) Auxiliary display
The auxiliary display area(4) is mainly designed for assisting the main display area(3) and it
can make all the bytes displayed by decimalism in area(4) instead of by hexadecimal in
area(3),which is very convenient for users to oberserve.
You can click the ‘Help’ in the software in order to get more help information;
for the more detailed direction for usage, please refer to software manuals.

Chapter 3 Radar Communication Protocol
1. Overviews
The radar outputs FEh FDh FDh FEh after power is on and reset, and then enters the speed
measurement state. The default measurement range is between 05h and F0h (corresponding to 5～
240km/h).The parameters of radar can be set after pressing the “Enter the setup” command, which
takes the radar into the configuration state. The radar can return to the measurement state when
pressing the “Exit the setup” after parameter settings are completed.
There are three kinds of working mode:
The first is continuous mode. The radar outputs a speed data with interval of 26 milliseconds
when the target is passing through the detection area, and outputs 00h when there is no target.
The second is trigger mode. The radar outputs data only when the target is detected and has
no output if there is no target;
The third is answer mode. The radar outputs the speed data only when the host computer
sends command for request (F7h) in the speed measurement state. The ex-factory setting is
trigger mode and the speed measurement data is a single byte.
Attention: The default of this equipment is the second mode.

Chapter 4 Maintenance and common fault judgment
The radar is the product applied to domain with high technique and high sensitivity. Please read
the direction of the product carefully before using.
1. Please use the high quality DC power supply voltage which could meet the requirements and an
independent power supply is needed to prevent crosstalk from other devices.
2. The positive side of the radar is the antenna radiating surface, so do not cover it when using.
3. Avoid shock and drop damage to the products, and prevent the product from rain,dust and lightning when
using.
4. Our company provides radar with RS232 interface and RS485 interface and they are not hot-
pluggable. Please turn off the power first to avoid accidental burns when connection .
5. RS232 and RS485 standards do not have clear and consistent rules for ports and lines sequence.
Please pay attention to their own definitions when connected between different devices.

Appendix 1 The correction calculation method of the target
speed
The radar measures the radial speed of the moving target relative to the radar. The component speed
of the target is

cosv
in the beam axis of radar , where theta is formed between the radiation
direction of the radar and the moving direction of the target. The measurement of the radar is this
component speed, which is called the radial speed.
As shown in figure 5.1.

Use the equation 5.1 for adjusting the speed by the users is determined by the
installation and usage condition.

Especially, the speed correction equation approximates equation(5.1) if the height
between the radar and the ground is lower(Eg, less than 3m) and the radiation almost is
horizontal(don’t need radiate to the ground because the target has a certain height).
