Effective Bartlett Output Spatial Spectrum of Updated Weight Signal

摘要

In this paper, we search for the desired signal among the received incident signals on the array antenna in the correlation environment. Bartlett method using the updated weight vector is applied to arrival direction estimation. The updated Bartlett method optimizes the output energyof received signal by applying an optimal weight. We use Bayesian probability and Wiener Hop equation to obtain the optimal weight value. Through simulations, we analyze the performance of the proposed algorithm and the conventional algorithm to estimate correct target. As a result of simulation,direction of arrival estimation ability of proposed algorithm is superior to the conventional algorithm, and proposed algorithm has good better resolution than the existing algorithm.
