摘　　要：雷达/干扰机一体化共享信号的波形设计是实现电子战中雷达/干扰机一体化系统能量共享的关键,针对混沌二相编码信号作为共享信号的不足,如自相关旁瓣过高、随机性程度不高、干扰效果不明显等问题。为解决上述问题,提出了一种新型的一体化信号优化设计原则,主要思想:以旁瓣及旁瓣能量极小化作为雷达信号设计依据,以混沌序列信息熵值极大化作为干扰信号设计依据,通过建立目标函数,对混沌序列进行遍历搜索。仿真结果表明,对于提高一体化共享信号的探测性能和压制干扰性能是可行的和有效的,为设计系统提供了参考。The waveform design for radar and jammer integration shared signals is the key of energy sharing for radar and jammer integration system in electronic warfare.Chaotic binary phase coded signal is presented as shared signals with several shortcomings,such as high correlation sidelobe,low random degree and ineffective interference performance.To solve the problem,a new optimization principle is presented to achieve shared signal optimization design,the main idea is that taking sidelobe and sidelobe energy minimization as the design basis of radar signals and information entropy maximization as design the basis of interference signals,chaotic sequence is searched by objective function.Simulation experiments show that the new method is feasible and effective to improve detection efficiency and interference efficiency of integration share signal.
