Aiming at the problem of limited information obtained by single-station location, a single-station time difference of arrival (TDOA) location algorithm based on scatterer-assisted single-station location under the condition of multipath propagation is proposed in this paper. The location of scatterers are known, and Chan algorithm of direct wave is applied to geolocation in non-direct wave environment. The simulation results show that the algorithm can achieve the goal of location with high accuracy and low complexity. It has a certain reference value for the engineering realization of target location in complex signal propagation environment.
