ABSTRACT:
A pulse chasing-type bistatic radar system is provided with a cluster of multiple narrow receive beams that covers the angle corresponding to the receive beam width required by the conventional pulse chasing mode, i.e., the required receive angle width, and scans in steps in accordance with the propagation of the transmit signals in the transmit beam. As the receive time-frame ends for the last narrow beam making up the cluster, it advances to a new position at the head of the cluster. Adopting this arrangement, the required number of receive beams can be reduced to the minimum.
