摘　　要：针对MIMO雷达体制的离散频率编码波形设计问题,给出了一种采用遗传算法对频率编码序列的选取进行优化组合的方法.首先对波形设计的代价函数进行了改进,然后针对离散频率编码的特点,对遗传算法的选择、交叉、变异算子进行了设计,最后对设计结果进行了分析.结果表明,该方法要优于模拟退火算法。Aimed at the designing issue of discrete frequency-coding waveforms in a MIMO radar system, a method to optimally combine the selection of frequency-coding sequence using the genetic algorithm was presented. First, the cost function of waveform design was improved, and the selection, crossover and mutation operator of genetic algorithm was designed in terms of the characteristics of discrete frequency-coding. Finally, the design results were analyzed, which shows that the proposed method outperforms simulated annealing algorithm.
