摘要
针对低分辨率雷达回波含有架次特征信息的状况,提出一种回波仿真方法.选用辛格函数作为散射中心函数,由多个散射中心函数的加权和逼近目标冲激响应,将发射信号与目标冲激响应卷积得到仿真回波.仿真回波对基于波形特征的编队目标架次判别的算法研究提供一定的数据支持.
In view of echo of low-resolution radar contains sortie signature, a method of echo simulation was proposed. The simulation echo was obtained by using a sinc function as the scattered central function, weighting multi-scattered central functions and approaching the target＇s impulse response, and convoluting the transmitted signal and target＇s impulse response. And the simulation echo can provide a certain data assistance for the algorithm of deciding formating target number.
