摘　　要：在雷达电子战一体化的需求背景下,针对传统雷达信号功能单一、易被截获以及干扰信号能量利用率低等问题,提出一种伪随机复合调制的探干一体化信号波形。文中构建了伪随机复合调制的探干一体化信号的信号模型,并对其模糊函数、伪随机序列的相关特性及其干扰特性进行理论分析,通过仿真实验证明,该一体化信号样式具有良好的模糊函数及频谱特征,非协作方接收到该信号呈现较强的噪声干扰,本地接收机通过匹配滤波,能够成功检测,具有良好的探测性能。Under the background of the requirement of integrated radar electronic warfare, a detection-jamming integrated signal design of pseudo-random composite modulation is proposed in this paper to solve the problems of single function, easy to be detected and low energy utilization of jamming signal. The detection-jamming integrated signal model of pseudo-random composite modulation was constructed, and the ambiguity function, the related characteristics of pseudo-random sequence and the interference characteristics of theoretical analysis. The simulation experiments show that the integrated signal style with a good ambiguity function and spectrum characteristics, the collaboration receives the signal present strong noise interference, while the local receiver through the matched filtering, successfully detection, has good detection performance.
