1.Introduction
ITS-AX2 barrier gate control radar is
developed for the entrance and exit
management of parking lots or underground
garages. It can precisely control the rising and
falling of the gate rod by cooperating with the
main control board of the gate control system,
which could effectively avoid the "accidental
injury" of the gate rod to the passing vehicles or
pedestrians in the radar field of view,and realize
intelligent anti smashing.
ITS-AX2 radar adopts the highly integrated
RF chip SOC scheme, which has the
characteristics of small size, low cost, all-weather
working capability, high detection sensitivity,
high precision, easy to debug&installation, very
good stability and reliability.

The working frequency of the radar is 79GHz,
with Linear Frequency Modulation and
Continous Waveform, which makes the available
bandwidth up to 4GHz. The range resolution is
up to 4cm, and ranging accuracy is better than
2cm. The radar antenna adopts multiple
transmitting and multiple receiving design that
enables the radar good angular resolution and
high angle measuring accuracy. The onboard
signal processing and control unit apply the
DSP&arm dual core architecture. Through the
joint optimization design of software and
hardware, this product can accurately identify
and distinguish the pedestrian, vehicle and other
targets passing through the brake lever area,
and avoid the phenomena of "smashing the
vehicle", "smashing the person" and "not
dropping the lever".

The appearance of radar is shown in Figure 1.
The main features are:
LED indicators：
There are two LED indicators on the surface of the
front of radar.
The red LED is the power state lamp which will stay on
when the power supply is turned on. The green LED is
the operating status lamp which will be automatically
trigger on when objects detected in the access area and
it goes off when there is no objects.
Detection Zone configuration:
The default detection Zone of the radar is 3 meters
forward times 0.5 meters on the left and right sides.
Different detection areas can be configured via mobile
APP or debugging software running on uphost
computer.
3.Features

Configuration parameters saving and reload:
Configuration such as detection area could be
automatically saved, and the latest configuration
parameters after power failure and restart will be
reloaded.
Firmware upgrade:
The firmware can be upgraded online through RS-485
or APP interface with host computer without taking off
the cover board and the new firmware can take effect
just by restarting the power of radar.
Stable performance:
Millimeter wave radar sensing capablity stay nearly the
same under different light illuminations, climates such
as rain, fog or snow and dust.

4.Installation Instructions
The radar must be installed on the surface of gate box
body and the radar surface with LED indicators must be
perpedicular to the lane (vehicle access) direction. The
installation must follow the instructions below:
Step1.Choice of radar mounting location.
the radar LED indicator must be facing down which
refers in Figure 2. The installation position of radar must
be 200-300mm away from the barrier gate and
550-750mm higher than the ground.

Figure2.Radar Installation Demonstration
Step2.Trepanning
A mounting hole of M16 should be drilled on the
surface of gate box according to the installation position
illustrated in the former part(see figure 2).
Recommended diameter of drilling hole must be
approximately 16mm.
Step3. Radar mounting and fixing.
(a)Put radar through the
circular hole
(b)Nut locking and fixing
M16 nut

(c)Post installation display
Figure 3. mounting and fixing steps schematic
As shown in Figures 3 (a)-(c), the radar is fixed to the
brake box through the bottom bolt. Firstly the radar is
plugged into the brake box, then cover the washer with
M16 screws to fix it, then insert the end of the wire
harness into the radar in the correct direction and lock
the metal buckle. The final installation effect is shown as
Figure 4.

Here are the detailed connections of these
interface to the gate control board.
Power supply connection:
The red wire("VCC") MUST be connected to the positive
output terminal of the 12V power supply,
The black wire ("GND") MUST be connected to the
negative output terminal of the power supply.
Barrier gate control signal:
The green and blue wires are normally open signals 1 of
the radar onboard relay1.
The brown and purple wires are normally close signals 2
of the radar onboard relay.
The control line wires MUST be connected to the
originally loop detector interface and the public
common signal interface.

RS-485 line connection:
gray line by line RS-485 T/R + end;
white line by line RS-485 T/R - end.
Bluetooth connection
bluetooth name: "Radar…";
user password: 88888888.

6.Configuration Instructions
The radar can be debugged through either
the mobile APP or the debuging software on
the uphost computer.
Mobile application debugging instructions:
After installing the debugging application to the
mobile phone, click the icon of the application and the
user interface is displayed as Figure 5. Click Connect
Device button as shown in Figure 6, and select "Radar..."
Bluetooth pairing connection

Radar parameters can be reconfigured
according to the actual circumstances and then
just record the the background clutter.

Other detailed operation can be found in the product
manual and application manual.
