    Abstract:

    Waveform design for detection and jamming integration is one of the key technologies to improve radar radio frequency stealth performance. This paper proposes two integrated waveform composite coding schemes, and Wigner distribution is utilized to analyze the jamming performance of the designed waveform. Firstly, the design scheme and signal model of frequency coding, phase coding and two composite coding waveforms are given based on chaos theory. Then, the detection performance is described by ambiguity function and the jamming performance is described by information distance based on Wigner distribution. Simulation results show that the designed integrated waveform can effectively improve the detection and jamming performances, and there exists a tradeoff relationship between the above-mentioned performances.
