1 General Introduction
ITARD-024SA is high-performance narrow-beam flat radar. It is an auxiliary product in the ITS
area of considerable integration and intelligent level. It is to detect the moving vehicle
dynamically to promote the modern management level of the road and city traffic.
ITARD-024SA realizes the vehicle detect via the Doppler effect theory. The radar sends out a ray
of microwave, and the microwave is reflected after it touched the moving vehicle. The radar can
receive the reflected wave. If the object has the radial movement relative to the radar, the
frequency of the reflected wave is different from the frequency of the send out wave. At the same
time, the difference of the frequency is proportion to the relative moving speed of the object and
the radar. Now the radar can detect the difference between the reflected wave and the send out
wave to calculate the moving speed of the vehicle.
The radar that used to detect the vehicle speed shall meet some basic requirements.
First, the antenna of the radar shall have sound direction capabilities. The wave beam shall not
be too wide. Otherwise, there are several lanes in the radar detect area at the same time; the
radar can not distinguish the object and can not calculate the speed. In the actual environments,
we can see the wave beam level width of the radar shall be less than 7°. The ITARD-024SA
adopts the 4.6°angle. To avoid the interference from the vehicle out of the beam, the side lobe
level of the antenna direction shall be general low. Usually it shall be less than －15dB. The
ITARD-024SA adopts －21.5 dB. At this value, it can effectively reduce the interference from the
neighboring lane. Besides, to accurately locate the vehicle position, the trailing edge of the radar
beam shall be steep, the typical and the wave beam-shape factor (－20dB width/－3dB width)
shall be less than 2.5.
The second requirement is speed measuring responsive time. It is the delay time from the object
enters the detect area to the radar gives the speed data. ITARD-024SA adopts the following
principles: for the vehicle of slow speed, the speed measuring responsive time is general long
and for the vehicle of high speed, the speed measuring responsive time is short. In this way, the
vehicles of all speeds are in the specified distance so that the camera can get the clear plate
information.

5 Installation
ITARD-024SA high-performance narrow beam flat radar detect min speed is 10Km/h. It can not
directly provide the vehicle direction. The width of the microwave beam level and tilt is less than
3dB and usually it is used in the ANPR (Auto Number Plate Recognition).
Step1
The radar shall be installed at the transverse arm (it is 5.5-7.5M height from the ground) at the
top of the lane. Please use three screws to fix the bracket and keep it standstill. See Figure 5-1.
Please secure these three
screws between the
pedestal and the bracket.
Figure 5-1
Step2
The antennae shall face the approaching vehicle. The radar wave beam shall have an angle with
the ground. Please adjust according to the project requirements and camera snap, usually the
distance from the centre of the radar monitor area to the projection ground distance of the radar
ranges from 10m to 20m.
Step3
Radar Installation Angle
For the environment of high traffic flow or strong wind, the recommend angle shall be 23°.It can
enhance the capture rate and performance is more stable. But the shortcoming is it can not snap
some vehicles that running on the traffic line and the vehicle snap position are about 15-17m.
If the traffic flow is low (such as the express road), the recommend angle shall be 22°.In this
situation, the capture rate may be lower than in the 23°, but the capture rate of the vehicles
running on the traffic line may be higher. At the same time, the snap position is general nearer. It
is about 16-18m. In this way, the camera can snap the human face.
Please note the above angle is for reference only. Please select the reasonable snap position.
Usually, the nearer the distance is, it is easy to distinguish the vehicles one by one. But the
speed error correction value may be high， and vice versa. Besides, the radar wave beam level
width is fixed 3dB. It shall guarantee the single-lane (There is no interference form neighboring
lane) and at the same, it can capture the vehicle running on the line. It has requirements of the
radar beam level angle. When the projection distance is far, the width of the level 3dB shall be
smaller. When the projection distance is near, the width of the level 3dB shall be larger. When
the distance is fixed, the width of the level 3dB is high if the you want the lane becomes width.
The narrow the lane is, the width of the level 3dB is smaller.
Please refer to Figure 5-2 and Figure 5-3 for ANPR installation information.
