摘要
通过对杂波特性的分析,特别是风对频域特性影响的分析,给出了三坐标雷达海杂波的信号模型。对该模型中各个影响因素进行了简要的分析,得出了频域去杂是最为有效的方法。针对杂波频域特征,提出了自适应频域滤波的算法,并给出了仿真结果。
This paper gives the sea clutter signal model of 3-coordinate radar through analyzing the characteristics of sea clutter especially the influence of wind on characteristics of frequency domain, briefly analyzes each influence factor in the model and fetches that declutter in frequency domain is the most effective method, aiming at the characteristics of clutter in frequency domain, puts forward the algorithm of adaptive frequency domain filtering and gives the simulation result.
