雷达干扰机一体化共享信号的优化设计研究

Optimization Research of Radar and Jammer Integration Share Signal Design

在雷达干扰机一体化系统设计中,通常选择随机二相编码信号作为其共享信号。但在实际应用中,随机二相编码信号存在旁瓣电平高、自相关旁瓣峰值过大,距离分辨率低,使用效果并不理想。为此,研究一种优选策略:建立优化目标函数,应用遗传算法进行二相编码的全局最优搜索,从中找出一组作为雷达干扰机一体化共享信号设计的最优二元序列组,使其同时满足雷达探测和干扰的目的。仿真结果表明,应用该方法优选的共享信号是有效、可行的。

In the design of radar and jammer integration system,we often use Binary Pseudo random sequences Phase encoding signal as the share signal.However,the signal results in practical applications is not ideal,such as high power frequency,high autocorrelation sidelobe peak,distance distinguish is low.Thus,the study of a optimization selection strategy：through the objective function design,with the genetic algorithm global optimum search,select the best Binary sequence for share signal design,to meet the functions of radar and jammer.The simulation experiment results show that the optimization share signal with this method is effective and feasible.
