Speed measuring device, radar system and speed measuring program

摘要

To shorten the measurement time of speed on a road surface or a water surface, etc., while maintaining accuracy of the speed measurement on the road surface or the water surface, etc., when the speed on the road surface or the water surface, etc., is measured using a radar.SOLUTION: Speed of the road surface or the water surface, etc., are measured at many positions without the need to perform integration processing in the time direction and without the need to rotate a radar antenna. Then, speed on the road surface or water surface, etc., at many positions are integrated to measure the speed of the whole road or water surface, etc. Here, Doppler speed of 0 in the direction parallel to the normal direction of the road surface or water surface, etc., is removed.SELECTED DRAWING: Figure 2
