基于压缩感知DOA估计的稀疏阵列设计
Design of Sparse Arrays Based on Compressive Sensing DOA Estimation
摘要
Abstract
According to the method of optimizing measurement matrix through Gram matrix,a sparse array design method for uniform linear array(ULA) based on compressive sensing direction of arrival(DOA) estimation is proposed.Without compressive sampling,this method can draw the DOA estimation results through the sparse recovery algorithm by using the output data of sparse array directly.The experimental simulation results show that,especially under the condition of less array elements and lower signal-to-noise ratio(SNR),this method has a better performance of DOA estimation compared with the original ULA.关键词
