Abstract: In order to develop a new locating system in CDMA network, this paper proposes a novel TSOA/AOA locating technique, which uses the measurements of Time Sum Of Arrival(TSOA) and Angle Of Arrival(AOA) to locate a move station. It sets up the mathematical model for TSOA/AOA locating, and presents a locating and tracking algorithm based on Extended Kalman Filter(EKF). The feasibility of the algorithm is verified in the simulation.

摘要： 为研制基于CDMA网络的新型定位系统，提出一种新的到达时间之和(TSOA)/到达角(AOA)定位技术，它利用信号TSOA与AOA实现移动台的定位。为研究高精度实时定位算法，建立TSOA/AOA混合定位的数学模型，推导基于扩展卡尔曼滤波器的定位算法，通过仿真验证其可行性。
