The Method Research On The Detection Of Signals And Estimation For DOA Based On The Vector Sensor

Signal processing based on the electromagnetic vector sensor array is an important research topic in the array signal processing, it is a very broad application prospects in areas such as communications, radar, navigation. First, the thesis had studied completely polarized signal detection problem based on the matched subspace detection theory, and studied detection performance under the background of white noise, single interference, the actual received signal direction of arrival (DOA) and the beam direction was not the same. Second, the thesis had studied the joint estimation of DOA and polarization parameters based on the single electromagnetic vector sensor, and used cyclic MUSIC algorithm and cyclic ESPRIT algorithm to estimate. Finally, based on the electromagnetic vector sensor array, the thesis used, the cyclic MUSIC algorithm and cyclic ESPRIT algorithm to estimated parameters for spatial coherent source of electromagnetic signal. Through computer simulation to prove that these methods had good signal selectivity, the ability of anti-interference and noise suppression.
