摘要：
A novel decoherence algorithm, called fourth-order cumulants-based improved Toeplitz matrices reconstruction (FOC-ITMR) method is presented to estimate two-dimensional (2-D) direction-of-arrival (DOA) of coherent signals. The FOC-ITMR method fully utilizes the information of received data between the whole two parallel uniform linear arrays (ULAs) and the changing reference element based on FOC. Compared with the previous works, the proposed algorithm can achieve excellent decoherence performance. The theoretical analysis and simulation results demonstrate the effectiveness and efficiency of the proposed algorithm.
