自适应杂波抑制的一种算法与实现

An Adaptive Clutter Rejection Algorithm and Implementation

雷达自适应杂波抑制的算法及其可实现性是雷达信号处理的一个重要问题。针对常见的功率谱密度为高斯型的杂波,先从理论上论述了一种基于最大平均改善因子的自适应杂波滤波器权矢量的计算方法和参差滤波器参差码的优化设计,并进行了仿真,验证了该算法的可行性和有效性。然后从工程实现的角度讲述了权系数库实现自适应滤波的方法并阐明了这种实现方法的优缺点。

Radar adaptive clutter rejection algorithm and realization are important things in radar signal processing system. Point to the command clutter who has a power spectrum density function of the Gaussian type, the paper firstly discusses a method based on the maximum average improvement factor to compute the weight vector of adaptive clutter filter, and optimal design of the filer′s stagger code in theory, the simulation has been done to test that the algorithm is executive and efficiency. And then the paper tells the method using the weight library to implementation adaptive filter in engineer implementation and its merit and defect.
