Abstract

Because some signals have W-disjoint orthogonality, this paper proposes a signal direction of arrival estimation method in underdetermined conditions. This method is mainly based on the principle that signals of different directions lead to different time delay between the sensors, construct a potential function by receiving signal phase difference, and local maximum value location of the potential function corresponds to the signal direction of arrival. The simulation results show that the method can still obtain better estimation results in the case of only using two sensors.
