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 reduce the impact of the strong signals on the weak ones. an orthogonal projection matrix is constructed by the robust steering vector ... https://www.pomyslnaszycie.com/laguna-3hp-c-flux-cyclone-dust-collector-on-sale/
