仅用TOA和方位角测量对三维运动目标的被动定位跟踪算法研究

Study on a Passive Locating and Tracking Algoring Based on TOA and Azing Measurement for 3-D Moving Targets

本文提出了一种基于ＴＯＡ（到达时间）和方位角测量的算法，详细分析了该技术的定位原理和可行性。在某些接收机以被动方法对三维运动目标定位跟踪的双基地雷达系统中，往往难以测量目标的俯仰角，因此本文提出的算法对于双基地被动定位系统的实用性具有很重要的意义。文中通过典型目标航迹的计算机仿真（按照ＭｏｎｔｅＣａｒｌｏ方法）对算法的性能作了评估。

This paper presents an algorithm based on TOA(Time of Arrival)and azimuth measure-ment.The location principle and feasibility of the technique are analysed in detail.For some bistatic radar systems in which receivers locate and track 3-D moving targets by means of passive method,it is sometimes difficult to measure elevation angle of targets.Therefore,the algorithm proposed in the paper is clearly of great importance to the practicability of passive location systems.The performance of this algorithm is evaluated by computer simulation(according to Monte Carlo methods)for typical target paths.
