摘要
针对相参积累过程中高速运动目标的距离走动问题,本文首先根据运动目标的回波特性,分析包络走动对积累性能的影响,然后提出一种通过调整匹配滤波系数进行分段补偿的方法。仿真实验通过补偿前后的相参积累结果对比证明了补偿方法的有效性。
Aiming at problem of range migration of high-speed moving target in process of coherent integration,influence of envelope migration on integration performance is analyzed firstly according to the moving target echo characteristic,and then a method of piecewise compensation by adjusting matched filtering coefficients is proposed.The simulation results show that the compensation method is effective by comparing the coherent integration results before and after compensation.
