TSOA/AOA is a new positioning system in CDMA cellular networks.This paper presents the principle of TSOA/AOA passive positioning with single equipment.The dynamics of the system under consideration are described by a nonlinear state-space model.Then,a passive mobile tracking technique is proposed based on particle filter,which is a powerful method dealing with highly non-linear/non-Gaussian problem.The technique allows for accurate estimation of Mobile Station's(MS) position and speed.The simulation results indicate this method can achieve higher accuracy than extended Kalman filter tracking algorithm.
