New Method of DOA Estimation in the Presence of Interference
A new direction of arrival(DOA) estimator in the presence of interference is presented in this paper.To suppress interference, the oblique projection is constructed with the prior knowledge of interference sources, which is used to filter undesired signals out.After filtering, DOAs of signals are estimated by the improved L1-SVD algorithm, in which the noise power is estimated to solve the optimization problem, so the prior knowledge on noise isnt necessary.The performance of the proposed method is evaluated by numerical simulations, and the effectiveness of the proposed method is proved..
