宽带L型非均匀阵的极化和到达角的联合估计
Joint estimation of polarization and direction of arrival based on the wideband L-shaped sparse array
摘要
Abstract
A high accuracy algorithm for direction of arrival (DOA) and polarization estimation for the wideband signal is proposed.The L-shaped sparse array is exploited in this method, which consists of multi baseline phase-polarization interferometers.Joint estimation is realized by utilizing direction and polarization information involved in the cross-correlation spectrum phase from the outputs of sensors with different polarizations in two linear arrays.It has the advantage of simple configuration which is suitable for realization.Parameter estimations are given by weighting and averaging the results from different baseline interferometers.The optimum weighting coefficients are given by the square of baseline lengths.Simulation results show the correctness of the algorithm.关键词
