Abstract :
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.
