Radar sensor
The Navtech radar sensor will detect both small and large objects, moving or stationary, within
its line of sight. It is designed to cover 360 degrees, and samples data at an angular resolution
of approximately 0.4 degrees. The radar antenna is designed to have a narrow beamwidth in
azimuth and elevation
– typically 1.8 degrees; in this way objects within the radar field of view
can be accurately located on the road surface.
The standard update rate for radar sensors is 120 rpm with a maximum detection distance of
200 meters radius. A signal return is produced and sent to the processing system every 0.25
meters from the sensor itself up to the maximum sensor range of 200 meters radius. This is
repeated at each new azimuth angle as the antenna rotates. The system employs a frequency
modulated sensor and so unlike Doppler systems, no movement is necessary to measure a
vehicle, person or similar object within the radar line of sight.
