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 4.6angle. 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. 1 2 Features Adopt flat micro beam array antenna design and manufacture technology. It can get the commonness easily, light weight and high efficiency. The speed measuring accuracy is high and the error ranges from -1km/h to +1km/h. High reliability. The level angle of the radar is small. In this way, it avoids the interference of reflected wave from the neighboring lane. Fast responsive time guarantees the capture rate and real-time feature. Advanced radar signal process and data real-time process technology. New algorithm, position is stable and the work can sustain. It can be widely used in many environments, fully supports the 2nd development. Low microwave radiation, low power consumption, long working hour, high stability and reliability. 2 3 Specifications Model Spec Antenna Type Radar Mechanism Microwave Working Frequency Send Power Antenna 3dB Beam Width AD Sampling Rate Working Mode Lane Amount Detect Info Capture Rate Speed Measuring Accuracy Speed Detect Range Communication Interface Cable Definition Power Input Power Consumption Interface Protection Working Environments Dimensions(MM) Unit Weight ITARD-024SA Flat micro beam array antenna Single-frame continuous beam 24.125GHz 50MHz 9.5dBm=8.9mW 4.6(H) 6.8(V) 25KHz Approaching Single-lane SpeedInstant 95%

Radar205mm*155mm*65mm Bracket163.4mm*100mm*155mm 1kg(Excluding bracket) 3 4 Dimensions Please refer to the following figure for detailed information. The unit is mm. See Figure 4-1. Figure 4-1 4 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. 5 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. Figure 5-2 Figure 5-3 Step 4 Connect the radar to the camera. Connect the radar to the camera via the RS232 port.
