Array Manifold Optimization and Multi-target Direction Finding Algorihm for Wideband Phased Array

To the problem of multiple direction of arrival(DOA) detection of the wideband receiver used for electronic reconnaissance,A novel direction finding technique is proposed in this paper.Adopted the optimal array manifold,to satisfied with both angle unambiguity and high resolution direction finding,and the snapshots DOA estimation in frequency is presented to estimate the DOA of multiple partial correlation targets and coherent targets,FFT is adopted firstly to detect target by threshold,and then DOA estimation is given based on the detected frequency,finally the simulation results show that the algorithm proposed is efficient and feasible.
