Parameter Estimation and Mutual Coupling Self-Calibration with Orthogonal Polarization Sensitive Array

Abstract

In order to address the mutual coupling impact with orthogonal polarization sensitive array, the mutual coupling self-calibration strategy is suggested in this study. Firstly, the mutual coupling properties are used to modify the steering vector of the array. By transforming the matrices, the properties of the polarization and direction-of-arrival (DOA) are isolated from the mutual coupling coefficients. Then, using the rank deficit matrix approach, the estimated the polarization properties and DOA values of the incoming signal are ascertained. The eigendecomposition of the transition matrix utilizing the modulus restrictions is then used to get the mutual coupling coefficient. The technique may be used to produce high-precision results of the mutual coupling coefficient when there is a substantial gap in the power of the signal sources. The outcomes of the simulation demonstrate the viability of the advanced method used in this work.
