An Airborne Radar Technique for Moving-Target Detection,Location,and Tracking.

摘要

A novel technique for detecting,locating,and tracking moving targets from an airborne radar platform is described and analyzed. The technique uses the generally dissimilar linear doppler frequency modulated signals from moving targets and stationary ground clutter. A matched filter processor is defined and its resolution and ambiguity properties studied as function processor parameters. Sub-clutter visibility of the processor is then determined. Two techniques for digitally implementing the processor are discussed and the computational efficiencies briefly analyzed. Finally,target angular position can be determined using phase monopulse. It is then shown that target velocity--both ground speed and target heading--can be determined from radar observables. (Author)
