It is an inevitable trend to provide accurate positioning of mobile users in 3D space for the future development of wireless communications. Based on the radar dual ranging principle, this paper first presents a radio method to realize the three-dimensional positioning of mobile users. Then based on the real-time, a fast algorithm to realize 3D positioning is discussed in detail. The simulation shows that the 3D spatial location algorithm meets the requirement of real - time and high precision. The single - point location simulation calculation only needs 0.13 seconds and the iterative error is less than 10 - 4
