ABSTRACT:
A testing circuit for a radar-operated vehicle safety assurance system includes a test signal generator for generating an artificial intermediate frequency return signal. The radar system is switched on a manual command signal from the normal operating mode to an under-test mode to accept the artificial signal to determine the speed of the vehicle relative to a hypothetical target and the instantaneous value of the distance to the hypothetical target. The radar system includes a vehicle roadway speed sensor which normally supplies the system with the instantaneous speed value of the vehicle. When the system is switched to the under-test mode, a signal indicative of a predetermined vehicle road speed is applied to the radar to determine the safety distance to the hypothetical target. When the instantaneous value of the distance to the hypothetical target corresponds to the safety distance, an alarm signal is delivered from the radar system. This signal is checked to see if it occurs within a preselected time interval so as to ensure that the radar system functions properly.
