摘要

低截获概率(LPI)脉冲压缩波形在安全通信中得到了应用。在存在非故意干扰的情况下,具有良好相关特性的传统波形不能满足要求。为了在提高LPI性能的同时满足安全通信对低旁瓣电平的要求,提出了混沌脉冲压缩码与错配旁瓣抑制滤波器相结合的方法。

Mismatched filtering of chaotic codes
Low Probability of Intercept (LPI) pulse compression waveforms find applications in secure communications. Conventional waveforms with good correlation properties fail to satisfy requirements in presence of unintentional interference. Chaotic pulse compression codes combined with mismatched sidelobe suppression filters are proposed to simultaneously improve LPI performance and meet low sidelobe level requirements of secure communications.
