For the problem of the direction-of-arrival (DOA) and source number estimations with coexisting strong and weak signals, a new method for robust estimations of DOA and the number of sources based on an optimized broad band sparse array is proposed.To Finding an Indigenous Perspective in Administrative Law reduce the impact of USE OF AUTHENTIC FILMS WITH SUBTITLES IN THE PROCESS OF LEARNING NEW VOCABULARY IN HIGHER EDUCATION SECTOR (AS BASED ON THE ENGLISH LANGUAGE MATERIAL) the strong signals on the weak ones, an orthogonal projection matrix is constructed by the robust steering vector of the current strongest signal.The proposed method has super-resolution and is robust to array mismatch.The effectiveness of the proposed method is demonstrated by the results of simulations.
