摘　　要：针对多目标环境下单平台和双平台无源定位系统无法消除大量虚假点难题,提出了一套基于三架飞机联合空间三角编队,并采用静态与动态相结合来滤除虚假点的多平台无源融合定位方法。该无源定位方式不需要飞机作机动,并能在多目标环境中快速有效地滤除虚假点,克服了单平台和双平台无源定位系统无法对多目标进行定位的缺陷,实现了系统全静默状态下同时对多个运动目标的融合定位与跟踪。给出了三平台无源组网对多目标融合定位与跟踪的实现结构、解算模型、误差分析以及虚假点滤除方法。仿真验证表明,该系统能实现对多运动目标的隐蔽探测、定位与跟踪,其跟踪精度能满足态势显示与火控攻击精度要求。In order to solve the problem that a lot of false intersection points appear in the passive location system based on one or two platforms in multi-target environment,a new passive location system based on three platforms is put forward in this paper,which forms triangular formation in space and removes false intersection points by combining static manner with dynamic one.This system doesn＇t need the airplanes to maneuver,and is able to remove the false points fast and effectively.It overcomes the defect that the passive location system based on one or two platforms is unable to locate multi-targets,and realizes the function that several moving targets are located and tracked simultaneously in a full silent state.The implemention structure,specific model algorithm,error analysis and the way of removing false intersection points are given in detail.The simulation results demonstrate that the system is able to detect,position and track multi-targets silently,and the accuracy of track can meet the requirements of the situation display and attacking.
