摘要
为解决低信噪比条件下检测前跟踪TBD算法对多帧雷达回波数据累计处理量大的问题,通过融合多种传统滑窗的性能特点,提出基于改进二维CFAR参考滑窗的单帧雷达回波数据检测器,得到了网格形参考滑窗。仿真实验表明,与传统滑窗相比,网格形滑窗在窗口大小为15时具备更好的检测精度和更高的实时性,验证了网格形参考滑窗的稳定性,为TBD算法实现前的数据处理提供了更好的处理技术手段。
In order to solve the problem that the track-before-detect(TBD)algorithm has a large amount of accumulated processing capacity for multi frame radar echo data under low SNR,a single frame radar echo data detector based on improved two-dimensional CFAR reference sliding window is proposed by fusing the performance characteristics of various traditional sliding windows,and a grid reference sliding window is obtained.The simulation results show that the grid sliding window has better detection accuracy and higher real-time performance when the window size is 15,compared with the traditional sliding window,which verifies the stability of the grid reference sliding window and provides a better processing technical means for the data processing before the realization of TBD algorithm.
