零自相关区相位编码波形设计
Designing Phase Coded Waveforms with Zero Autocorrelation Zone
摘要
Abstract
This paper discusses the design of phase coded waveforms with ultra-low autocorrelation sidelobes in desired inter-vals .These waveforms can be used as interference suppression and signal synchronization waveforms for radar ,sonar and communi-cation systems .An algorithm based on power spectral density (PSD ) approximation is proposed .According to the relationship be-tween aperiodic autocorrelation sequence and the waveform PSD ,the autocorrelation design object is translated into a PSD design object .The method transforms and projects the design waveform in the time and the frequency domain iteratively .Thus the PSD of the design waveform approximates the ideal PSD iteratively in order to generate the desired waveform .Compared with the general nonlinear programming methods ,this method is derivative-free ,thus requires less computer memory ,and the iteration can be imple-mented by FFT efficiently .关键词
