It is used to install an overspeed snapping system on the side of the road, which can detect illegal vehicles in 1-4 lanes. Narrow beam, accurate speed and location, can distinguish the direction and direction of vehicles. The speed of the body and target vehicle can be measured in motion. Small narrow fluctuating dynamic velocity radar is a multi-purpose radar, which has the characteristics of wide lateral angle and narrow longitudinal angle. It is suitable for multi-lane situation. The main application scenarios are roadside mobile electronic police or fixed-point overspeed capture system, top-mounted multi-lane jammed overspeed capture system.

1, roadside mobile electronic police or fixed point speeding capture.

The horizontal angle of multi-lane narrow-wave velocity radar is designed to be 4.5 degree narrow beam, which ensures the triggering position is accurate, can effectively distinguish continuous vehicles and overcome the interference caused by multiple vehicles entering the beam range at the same time. A single radar can cover multiple lanes by oblique illumination, and distinguish the direction from the direction of the vehicle, so as to carry out direction screening and retrograde snapping.

2, top mounted multi Lane bayonet overspeed snapping line

Use a radar to monitor multiple lanes simultaneously. Radar is installed in the middle of the upper part of the road. According to the different road conditions, each radar can monitor 2-4 lanes. Because the longitudinal angle of the radar is only 4.5 degrees, the radar has the advantages of small detection area, effective discrimination of continuous vehicles and accurate triggering position.
