Yi Qin, Xiangyang Chen · Journal of Physics Conference Series · 2023
Abstract In order to efficiently and accurately estimate the direction of arrival of coherent signals, a Toeplitz estimation method based on eigen space multiple signal classification (MUSIC) algorithm is proposed. Firstly, the coherent signal is processed by Toeplitz, and then the MUSIC algorithm of the eigen space is used to estimate the DOA accurately. The computer simulation results show that the method can realize the accurate estimation of the angle under the condition of signal coherence, and the accuracy is improved compared with some other algorithms.
