基于GA的数字单脉冲雷达相位误差的校正

摘要

为校正数字单脉冲雷达跟踪系统各通道存在的相位误差,针对传统遗传算法在对目标来波方位和相位误差进行估计时可能存在早熟等缺点,提出了将改进的遗传算法运用到估测阵列相位误差的方法中.在对相位误差估测同时对原导向矢量进行了修正,系统得到了更为准确的信号波达方向估计值和较好的跟踪效果.通过计算机仿真,验证了算法的可行性和准确性.%For the problem of premature convergence on the traditional genetic algorithm, to overcome the phase error in digital monopulse radar tracking system, the new genetic algorithms are put forward. The steering vector is modified to get the more accurate Direction Of Arrival (DOA) of the signals and good tracking performance. The simulation results are presented to show the feasibility and validity of the algorithm proposed.
