Abstract
PURPOSE:To make it possible to measure the absolute moving speed of a moving object even when a vehicle mounted with a radar system speed detector is at rest, by providing said vehicle mounted with a detector for detecting the stoppage thereof. CONSTITUTION:A relative moving speed between a vehicle B mounted with a radar system speed detector 1 and a moving object A to be measured in speed is measured through said detector 1. An arithmetic device 3 carries out operation according to said relative moving speed and the speed of the vehicle B obtained through a vehicle's own speed measuring device 2 and a vehicle stoppage detector 5 in order to determine the absolute speed of the object A. On the other hand, detecting the stoppage of the vehicle B, the detector 5 controls the arithmetic device 3 so that the speed of the object A is measured only by means of the output of detector 1. Accordingly, it is possible to measure the absolute speed of the moving object even when the vehicle mounted with the speed detector is at rest, without making said vehicle run at a speed more than a given value.
