摘　　要：良好的反侦察性能是军用无线通信系统区别于民用无线通信系统的重要指标之一。提出了一种时频码联合捷变的通信波形,研究了其波形设计、捷变控制与同步接收方法,并对该波形的反侦察性能进行了仿真分析。理论分析与仿真结果表明:与传统的常规扩谱通信信号相比,时频码联合捷变通信波形的检测概率降低了90个百分点左右。Anti-reconnaissance performance is an important indicator which distinguish military wireless communication system from civil wireless communication system.A joint time-frequency-code agile waveform was proposed,and the waveform design,agile control and synchronous receiving method are studied.The anti-reconnaissance performance of the waveform is also analyzed.The theoretical analysis and simulation results show that the detection probability of the proposed waveform is reduced by about 90 percentage point compared with the conventional spread spectrum communication signals.
