Radar Clutter Reduction by Use of Frequency-Diverse, Wideband Pulse-Compression Waveforms.
Abstract
A method is given for generating and transmitting wideband, expanded radar pulses which spatially decorrelate clutter and are frequency-hopped from pulse to pulse by the proper frequency difference for clutter decorrelation by frequency-diversity. The returned signals are compressed, delayed by one pulse interval, and correlated, each with its succeeding echo pulse, to decorrelate the clutter returns but not the target echoes. The frequencies of the transmitted pulses are locked to the local oscillator frequency, which is very stable. A double-sideband technique is used to generate the different pulse frequencies. (Author)
