ABSTRACT:
Radar systems in which target detection and unambiguously measured range rate are derived from returns from a high pulse repetition frequency (PRF) transmitted waveform; and wherein a lower PRF waveform is adaptively selected as a function of the measured range rate so that the range of even targets, that might otherwise be obscured by clutter, is unambiguously measured. For high PRF track update for a target on which track file data has been established, predicted range is used to adaptively select a high PRF waveform which avoids eclipsing of target returns due to the receiver being non-receptive during the transmission mode.
