Abstract

Abstract:

As for the waveform cluster design of wideband orthogonal low probability of intercept (LPI) radar, utilizing the composite waveform coding technology of frequency coding agility and frequency modulation slope agility, a nonlinear cost objective function of compound frequency coding is constructed based on waveform orthogonal constraint. Moreover, the optimization design method of composite waveform cluster combining frequency coding agility and frequency modulation slope agility is proposed. A wideband orthogonal LPI waveform cluster with optimal autocorrelation and cross-correlation sidelobe is obtained by using pattern search algorithm. Simulation results show that the designed waveform can obtain low autocorrelation sidelobe and low cross-correlation sidelobe, which can provide reference for the design of LPI radar transmitting waveform and multiple input multiple output radar waveform.

Key words: low probability of intercept (LPI) radar, orthogonal waveform, low autocorrelation sidelobe, low cross-correlation sidelobe
