    摘要:

    探测干扰一体化波形设计是提升雷达射频隐身性能的关键技术之一。本文提出了两种探干一体化波形复合编码方案,并联合Wigner谱分析所设计波形的干扰性能。首先,基于混沌理论给出频率编码、相位编码及两种复合编码波形的设计方案和信号模型。然后,利用模糊函数描述波形探测性能,利用基于Wigner谱的信息距离描述波形的干扰性能。仿真结果表明,设计的一体化波形能够有效提升波形的探测和干扰性能,同时验证了探干性能间存在折衷关系。

    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.
