| 摘 要： | 风廓线雷达去地杂波一直是一个较难解决的问题,基于提升小波理论的滤除风廓线雷达地杂波信号具有很多优势,例如抑制杂波效果好、运算量小、易于工程实现等。介绍了提升小波理论,然后分析风廓线雷达信号特征,提出提升小波去地杂波方法,最后给出仿真结果和结论。这种方法将被应用于某型在研边界层风廓线雷达实时信号处理中。

| Abstract: | Removing clutter in radar wind profiler is still a difficult problem to solve,while removing clutter based on lifting wavelet has proved to be of many advantages,such as good effect on removing clutter,high numerical efficiency,and easy way to realize,and so on.After introduction to the general theory of lifting wavelet,the signal characteristic of radar wind profiler is analyzed.Thereafter lifting wavelet method of removing clutter is proposed.Finally results of simulation are shown with some figures and conclusion is drawn.The proposed method will be applied in its real-time signal processor of a certain boundary layer radar wind profiler which is being manufactured. |
