| 摘 要： | 介绍了基于改进型遗传算法的滑动参差MTI滤波器优化设计。采用滑动脉冲的方式进行MTI滤波器设计，利用改进型遗传算法搜索最优参差码，有利于检测陷在滤波器第一零点里的弱目标。同时该滤波器可形成凹口以滤去杂波，并将盲速推到3倍音速以外。由于采用改进型遗传算法对参差码进行搜索，使运算量大大减少。仿真结果和性能分析验证了算法的可行性和有效性。

| Abstract: | A novel slipping stagger MTI filter design based on the improved genetic algorithm(IGA)is presented.The filter is designed by slipping pulses and the optimal stagger code is selected by IGA,so the weak target in first notch can be detected.Multi-model clutters can be rejected by the slipping stagger MTI filter,and blind velocity can be beyond three times the velocity of sound.To decrease the computation,the improved genetic algorithm is adopted to search stagger code.The simulation and performance analysis ... |
