Research On Method Of Polarized Array Doa And Parameter Estimation

Use electromagnetic vector sensor array to locate the source estimated that is a new branch in the field of modern signal processing, How to actual use it in radar, defense, communications, aviation and other fields is becoming a hot issue of scholars’research.This paper research several DOA Estimation and polarization estimation method by electromagnetic vector sensor linear array, compared with the traditional array signal estimation method, whether to have more noise suppression capabilities and higher performance parameter estimation. Construct the circulation fourth order cumulant matrix for the electromagnetic vector sensor model and combine with the traditional DOA and polarization parameter estimation method to create a new method HOCS-MUSIC and HOCS-ESPRIT.This two algorithms have a better ability to suppress the noise, and simple arithmetic, higher precision, and finally make the MATLAB simulation experiments prove its advantages.
