基于 OMP 算法的极化敏感阵列多参数估计
Multi-Parameter Estimation for Polarization Sensitive Array Using Adaptive-OMP Algorithm
摘要
Abstract
The DOA estimation algorithm based on compressive sensing has superior performance in small snapshot and the natural ability of decorrelation,but it is rarely used in the polarization sensitive array. In this paper,an improved OMP algorithm based on polarization sensitive array is studied to estimate the pa-rameters of the air domain and the polarization domain.First,this algorithm remodels the signal receiving matrix of the polarization sensitive array,followed by using the proposed improved OMP algorithm to obtain the estimation results of spatial arrival angle.Then,the polarization parameters are estimated via the closed solution to a cost function of the mold constructor constraint,in which the estimated spatial arrival angle is substituted.Simulation results show that the proposed method can obtain good results in both coherent and incoherent signals and the estimation performance in the case of incoherent signals is generally better than the polarization ESPRIT algorithm and the modulus constraint MUSIC algorithm.关键词
