Efficient DOA Estimation Method for Wideband Uncorrelated Signals

An efficient DOA estimation method for wideband uncorrelated signals is presented in this paper. Compared with the focusing Khatri-Rao subspace method, the computation burden of the method degraded greatly due to using the technique of uniform focusing. Moreover, the method can resolve more signals than the number of array elements and have higher performance. Simulation results demonstrates the effectiveness and efficiency of the method.
