Study of a Class of Detection Waveforms having Nearly Ideal Range-Doppler Ambiguity Properties.

摘要

A special class of permutation matrices is considered. It is shown that these matrices may be beneficially used to determine the frequency-time pattern of a uniform pulse train. Proper choice of burst waveform parameters is shown to result in a detection waveform having range and doppler resolution properties consistent with the overall signal duration and bandwidth. The range-doppler sidelobe peaks are well-controlled so that the ideal 'thumbtack' ambiguity function behavior is closely approximated by the synthesis procedure presented. (Author)
