Abstract: A radar system includes a clock for generating timing signals of a predetermined period, an exciter for generating high frequency signals of predetermined frequencies in sequence and in time series in response to the timing signals, a transfer switch and an antenna. The transfer switch has an input terminal and a plurality of output terminals. The input terminal receives the high frequency signals and provides one of these high frequency signals at each of its outputs in accordance with the received timing signals. The antenna is connected to receive the high frequency signals from the output terminals of the transfer switch to form radar beams corresponding to the high frequency signals.

Abstract: A radar system comprises means for forming a transmission pulse signal as m sets of n pulses, the individual sets having respective PRPs Ti (i=1, 2, . . . , m) moving target detection means, and angle measurement means utilizing beam-to-beam amplitude comparison and interpolation for a given moving target. Beam-to-beam amplitude comparison and interpolation is carried out at least twice for one target by making use of a pair of video signals with the same PRP processed by the moving target detection means. The angle measurement is achieved through a predetermined correlation processing over thus obtained interpolated angle values for a target.
