基于改进匹配追踪算法的风轮机杂波抑制
Clutter suppression of wind turbines based on improved matching pursuit algorithm
摘要
Abstract
In order to solve the problem that wind turbine clutters affect the search and tracking of radar tar-gets,a wind turbine clutter suppression method based on an improved matching pursuit algorithm is proposed.Firstly,the wind turbine clutter model is established.Then to address the problem of excessive computation caused by redundancy in dictionary matrix in traditional matching pursuit algorithm,the Artificial Bee Colony al-gorithm is used to roughly estimate the atomic parameters in the dictionary matrix.The range of the parameters is reduced to form a new dictionary matrix while the parameter accuracy is ensured.An improved matching pursuit algorithm is proposed and applied to the clutter suppression of wind turbines.Finally,simulation verification is conducted.The results show that the improved matching pursuit algorithm has higher operational efficiency com-pared with the traditional matching pursuit algorithm,and that it is effective to use the improved matching track-ing algorithm to suppress the clutter of wind turbines under different SNR.关键词
