用于卫星干扰源定位的压缩感知DOA估计方法
Satellite Interference Localization Method Based on the Compressed Sensing DOA Estimation
摘要
Abstract
The conventional direction finding methods have poor performance in the actual application. A satellite interference localization method based on the compressed sensing theory(CS)is proposed. Based on the interference signal angle’s sparseness in angle space, the corresponding direction of arrival(DOA)model is constructed. This method approximates the signal subspace through the high-order power of the spatial covariance matrix. Then the column vector in the lower left corner of the main diagonal of the high order power matrix is extracted to do DOA estimation. The experimental results show the method is better than the MUSIC algorithm in the aspects of resolution, accuracy,and capability of estimating coherent signals without the number of signals. This promotes the application of compressed sensing in satellite interference localization.关键词
