摘要

本文对超视距目标定位与跟踪问题进行了研究

并给出了一种把主动跟踪技术和无源时差定位技术结合起来对超视距目标进行侦测的新方法.该方法的定位系统由地面站和空中站组成

地面站上的无源侦收设备测得经空中站转发(或反射)的目标信号到达时间差

同时地面站上的主动雷达对空中站进行精密定位

计算出目标信号在这段距离上的传播时间

进而可获得目标信号到达空中站的时间差

此时就相当于在空中站的位置对目标进行超视距侦测

利用时差定位技术就可估计目标的位置信息.通过仿真分析可看出

利用本文的方法可对超视距目标进行良好的定位与跟踪.

Abstract

This paper studies the location and tracking problem of the over-the-horizon target(OTHT).A new method is proposed

which uses active tracking technology and time difference of arrival (TDOA) location method to track the OTHT.This location system is composed of several air platforms and ground stations.The target signal is transmitted (or reflected) by air platforms and received by ground stations.TDOA information is measured by ground stations.At the same time the position of air platform is located by active radar in ground station.Then the time of target signal propagated between air platform and ground station is obtained.By simple calculation we can obtain the TDOA information of these air platforms

which is used to locate the OTHT.Simulation results show that the OTHT can be located and tracked by the method proposed.
