  • 摘要: 比幅单脉冲最大似然算法(ACM-ML)在进行目标参数估计时需要进行距离与速度的2维松弛迭代搜索,导致了计算效率低、运算量大的问题。针对上述问题,该文提出一种基于空时级联单脉冲的高效多目标参数估计算法(M-STCMP算法)。该算法将单脉冲概念引入脉冲域,利用时域单脉冲计算目标速度,避免了ACM-ML算法中对速度的迭代搜索,将2维松弛迭代搜索降为1维搜索,有效降低了计算复杂度。考虑时域单脉冲无法同时匹配分布在不同时域主波束的速度各异的多个检测目标,进一步利用目标信号的多普勒信息,在各多普勒单元分别进行时域单脉冲测速,并搜索目标距离值。最后为抑制目标间的信号泄露,将所有目标的估计参数进行级联迭代获得高精度参数估计值。理论分析和仿真结果验证了M-STCMP算法的有效性。
