A radar system for detecting hazardous objects has a transceiver including a transmitting antenna for transmitting microwave power. For a side detection system, power transmission is available when the vehicle is moving forward. A signal processor receives a pulsed vehicle speed signal and a reverse signal and is programmed to terminate transmission when no speed pulse is received for a preset time or when the reverse signal is present. The transmission is terminated by removing power from the transceiver or by rerouting the microwave power from the antenna to an internal calibration circuit. Radar transmission is re-enabled when the vehicle begins to move forward again. For a rear detection system, radar transmissions are enabled when the reverse signal is present.
In a vehicle having a radar system for detecting a possible collision, the method of radar power control comprising the steps of:
In a vehicle having a speed signal generator, an automotive radar system for sensing nearby objects wherein radar transmission is disabled when the vehicle is stopped comprising:
