Abstract :
A novel DOA estimation algorithm based on MP decomposition has been proposed. The atom dictionary of the new algorithm is based on the array geometry, and the algorithm is applicable for any phase differentiable signals, both wideband and narrow band signals. Computer simulations demonstrated that the accuracy of this algorithm is better than the algorithm based on WVD.
