摘要
通过对MIMO雷达动目标检测器的结构进行分析,提出了一种针对MIMO雷达动目标检测的快速算法。该算法通过借助快速傅里叶变换实现每个通道的动目标检测,从而缩小搜索范围,显著地减少了运算量,很好地解决了原算法因运算量过大而难以实时实现的问题。理论分析和仿真实验证实了快速算法的可行性。
A fast algorithm of MTD in MIMO radar is presented by analyzing the structure of detector for moving target in MIMO radar. The implementation of MTD in every channel through the FFT is adopted in this fast algorithm, thus, the searching scope is decreased,and the operation is reduced evidently, which overcomes well the problem that the original algorithm is hard to realize in real time because of great computation workload. The feasibility of the fast algorithm is verified by with theoretical analysis and computer simulation.
