雷达自适应杂波抑制的算法及其工程实现是雷达信号处理系统的一个重要问题。本文首先从理论上讨论了一种基于最大平均改善因子准则的动目标显示滤波器最佳权矢量的计算方法,然后从工程实现的角度提出了一种简单实用的具有双模杂波抑制能力的准自适应动目标显示系统,并将该自适应杂波抑制算法应用到实测雷达数据上,实验结果表明该算法对真实雷达回波中的杂波具有有效的抑制作用。
Adaptive radar clutter suppression algorithm and realization are important things in radar signal processing system. A calculational method of optimal weight vector of the moving target indication (MTI) filter based on the maximum average improvement factor criterion was discussed in theory, a simple, practical near adaptive MTI system with bimodal clutter suppression ability was proposed from engineering angle, and a adaptive clutter suppression algorithm was used for measured radar data on the spot. Results of applying the adaptive clutter suppression algorithm on real radar data demonstrate that the algorithm gives the effective suppression of the clutter in real radar echoes.
