摘　　要：针对未来空战中航空集群协同无源时差定位编队构型确定问题,提出了一种确定三机协同无源时差定位最优编队构型的方法。分析了确定集群编队构型的基本原理;归纳了4个三机编队构型决定因素:主辅机相对位置、基线夹角、基线距离以及主辅机高度差;将定位区域范围和定位距离作为衡量集群无源定位编队构型优劣的指标,并进行了仿真计算。仿真结果表明:在火控引导阶段,当采用主机在后、辅机在前,基线夹角为150°,基线距离为60 km^80 km,主机与目标同高度且主辅机之间高度差为±(1-2)km的编队构型时,三机协同无源时差定位编队构型为最优。To find out the way to determine on formation configuration of aircraft swarms cooperatingpassivelocationusingTimeDifferenceof Arrival(TDOA),thisthesisputsforwarda methodto determine theoptimal formation configuration of three-aircraft cooperating passive location using TDOA.Firstly,the basicprinciple to determine on formation configuration of aircraft swarms is analyzed.Secondly four determiningfactors of formation configuration,including the relative position between the chief aircraft and the assistantaircraft,the angle of baseline,the length of baseline and the height difference between the chief aircraft andthe assistant aircraft,are summarized.Thirdly,position range and position accuracy are used as twoevaluating indicators for the performance of aircraft swarms cooperating passive location using TDOA.Thesimulation results indicate that:in the fire-control-guidance stage,when the formation configuration isadopted,where the assistant aircraft is forward while the chief aircraft backward,with the angle of baselineset to be150毅,the length of baseline in the range of60to80km,and the chief aircraft as high as the targetwhile the height difference between the chief aircraft and the assistant aircraft controlled in依(1-2km,theoptimalformationconfigurationofthree-aircraftcooperatingpassivelocationusingTDOAcanbeobtained.
