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明显地具有很重要的意义。文中通过典型目标航迹的计算机仿真 (按照Monte Carlo方法)对算法的性能做了评估。
In this paper, an algorithm based on TOA (Time of Arrival) and azimuth measurement is proposed. The principle and feasibility of this technique are analyzed in detail. It is often difficult to measure the pitch angle of a target in a bistatic radar system where some receivers position and track three-dimensional moving targets in a passive manner. Therefore, the proposed algorithm is obviously of great significance for the practicality of the bistatic passive positioning system . In this paper, the performance of the algorithm is evaluated by computer simulation of typical target track (according to Monte Carlo method).
