摘　　要：针对常规MTD处理中未考虑相参积累期间目标与雷达相对运动引起的多普勒频率变化补偿问题以及其他运动补偿方法存在的不足,构建并分析了多普勒频率变化与目标运动加速度、角速度的关系模型;提出了一种先进行粗精两级搜索补偿、再进行MTD处理的新算法。该方法补偿策略清晰、计算量小且易于工程实现。模拟仿真结果表明,该算法的积累效果不仅要远优于非相参积累和常规MTD积累,且运算量也仅为已有补偿算法的数十分之一。For the problems that conventional MTD processing does not take into account the Doppler frequency variation compensation caused by the relative movement of the target and the radar during coherent accumulation,the relational models of Doppler frequency variation with target motion acceleration and angular velocity were constructed and analyzed.A new algorithm of approximate and subtle compensation two-stage searching firstly,and MTD processing secondly was proposed.The advantages of this method were clear compensation strategy,simple structure,and easy to implementation.Simulation results showed that the accumulated effect of this algorithm was much better than that of the non-coherent accumulation and conventional MTD accumulation,and the computation was only one part of dozens of existing compensation algorithms.
