چکیده

In this paper, in order to reduce the probability of radar waveform intercepted by passive detection system, time-bandwidth product is increased, and target improved. This paper tackles holographic RF stealth proposes a joint coding based on linear frequency modulation (LFM) waveform. Joint uses complementary codes perform phase-coding, combines codewords optimized genetic algorithm discrete frequency-coding The model theoretically analyzed, ambiguity function, pulse compression are obtained numerical simulation. addition, complexity low intercept (LPI) characteristic analyzed. results show that has an approximate “pushpin” ultra-low sidelobe characteristics, better performance. Finally, it good application prospects current battlefield environment.
