<p>In a pulse radar apparatus the transmitter is designed to generate similar transmitter pulses employing a plurality of pulse repetition periods, and the receiver, designed to transform detected echo signals, comprises: a switching-pulse generator (2) suitable for generating in several pulse repetition periods, at least a portion of a switching-pulse series each pulse repetition period, which portion is associated with switching intervals related to certain successive range sectors; a distributor (3) controlled by said switching-pulse generator (2) for selecting video signals in range sectors; and MTI filter units (4A-4B) connected separately to the distributor (3) for generating Doppler signals, representative of moving targets, from the video signals supplied by selection.</p> |
