In this paper,a rough way about AOA's reconstruction based on the single scattering model is presented.Then the information about multiple scattering path's time of arrival(TOA)and angle of arrival(AOA) are measured by a single base station,and Statistical properties of the model scattering are used to expand the method of the AOA's reconstruction algorithm to reconstruct the TOA using maximum likelihood estimation.The traditional model of single target parameter reconstruction is improved,and the single base location in the condition of non-direct wave is implemented with high accuracy.The simulation results show the effectiveness of the algorithm and confirm that the algorithm in the dense multipath environment has better positioning performance than in sparse multipath environment.
