    Abstract:

    For the influence of distance deception jamming on radar detection performance, the orthogonal characteristics of radar signals should be satisfied in waveform design, and radar waveforms should have lower cross-correlation and auto-correlation side-lobes. The chaotic binary-phase coded Orthogonal Frequency Division Multiplexing(OFDM) radar signal with good autocorrelation characteristics is adopted, then an orthogonal chaotic binary phase coded OFDM radar signal based on chaotic particle swarm optimization is proposed. The joint optimization of auto-correlation and cross-correlation is used as fitness function,the orthogonal coded pulse sequence signals are designed by using chaotic particle swarm optimization. The simulation results show that the chaotic binary-phase coded OFDM radar based on chaotic particle swarm optimization has a good cross-correlation and auto-correlation side-lobes whose maximum value is -22.33 dB, and it has a certain effect on the anti-distance deception.
