| Abstract: | We generalize a new incoherent wideband direction-of-arrival(DOA)estimation algorithm that provides higher resolution than traditional incoherent techniques. The new method is able to better adjust its beam response when multiple sources are present than incoherent MUSIC. The original algorithm was designed to work strictly for an uniform linear array. In this paper, we demonstrate how to generalize the algorithm to work over arbitrary 1-D or 2-D arrays. We demonstrate the higher resolution of the new algorithm against incoherent MUSIC for 1-D and 2-D arrays using simulations of two source signals. | ||
