ABSTRACT:
An FM-CW multibeam radar apparatus includes a plurality of antennas designed to serve both for beam transmission and receiving are arranged in such a manner that radiated beams overlap in part with each other. For sensing a short-distance-away target, a beam is transmitted by means of one of the antennas and a reflected beam is received by a separate adjacent one of the antennas to thereby obtain a beat signal. For sensing a long-distance-away target, one and the same beam transmitter-receiver is used. Upon sensing the short-distance-away target, the per-unit-time amount of change of the frequency of a frequency modulated transmitted signal is set to be larger than that for sensing the long-distance-away target so that a beat signal becomes higher, whereby the distance resolution is improved.
