| 摘 要： | 为了抑制或规避雷达编队中同型雷达发射信号之间产生的同频干扰，通常设计具有低自相关和互相关的正交信号是雷达编队抗同频干扰的关键。针对调频编码脉冲雷达信号的特点，提出了新的雷达编队抗同频干扰信号处理方法，应用遗传算法对调频编码序列进行优化选取，从中找出具有低自相关和互相关性能的几组正交编码组，以规避同型雷达间的同频干扰现象。仿真结果表明，该方法是有效的和可行的。

| Abstract: | In order to avoid or overcome co-channel interference in the same frequency radar formation,the radars must transmit specially designed orthogonal signals,so the key of anti-jamming is to design with low autocorrelation and cross-correlation signals.Aimed at the characteristics of frequency-coding,a new method of signal processing for radar formation to resist co-channel interference is proposed,genetic algorithm is used to optimize coding sequence of the co-channel radar signals,which designed with good autocorrelation and cross-correlation properties of orthogonal signals,to resist co-channel interference.Simulation results show that the method is effective and viable. |
