Abstract:
A vehicle mounted radar apparatus comprising:an oscillator for generating electromagnetic waves;a transmitter for transmitting the electromagnetic waves generated by said oscillator to a target;a receiver for receiving electromagnetic waves reflected from the target;an antenna for use with said transmitter and said receiver;a switch for connecting said transmitter to said antenna during transmission of the electromagnetic waves, and for connecting said antenna to said receiver during reception of the electromagnetic waves;a signal processor for calculating a distance between the vehicle and the target, and also a relative speed between the vehicle and the target based upon the electromagnetic waves transmitted to the target and the electromagnetic waves reflected from the target; anda power supply interrupter for interrupting supply of a voltage to only said transmitter;wherein during reception of the electromagnetic waves, said power supply interrupter interrupts the supply of voltage to said transmitter to thereby prevent transfer of the electromagnetic waves from said transmitter to said receiver.
