Pulsed Polyphase Signals with a Zero Autocorrelation Zone and an Algorithm for Their Compression

摘要

A polyphase (p-phase, wherepis a prime number) radiolocation signal that has an area of zero sidelobes in the vicinity of the central peak of the autocorrelation function has been synthesized. It is shown that this signal is a burst ofpcoherent phase-code-manipulated pulses coded byp-aryD-code complementary sequences. A method of forming a set ofp-aryD-code ensembles is proposed for synthesizing this signal. The correlation characteristics of the synthesized signal are considered. A compression algorithm for the signal, which includes a superposed fast Vilenkin-Crestenson-Fourier transform algorithm, is presented.
