摘　　要：针对自卫式干扰条件下火控雷达网的目标定位问题,依据测向交叉定位原理,建立了火控雷达网测向交叉三维定位模型,分析了影响测向交叉定位性能的各种误差源,在此基础上,建立了火控雷达网测向交叉三维定位精度模型,以此对自卫式干扰下火控雷达网的定位精度进行仿真分析,验证了在自卫式干扰条件下,火控雷达网采用测向交叉定位方法可以有效地对目标干扰源进行定位。Based on direction-finding location method,an efficient solution for self-defense jammer location by two spatially distributed radar stations in fire-control radar net is presented.Extraordinarily,the radar station location error is referred,and especially the system time synchronization error is originally discussed here.An innovative mathematics model of the jammer location precision is presented and facilitates the system location performance analysis,and formulae are provided for the modeling.Performance evaluation results are presented for various conditions,and indicate that the method is available for effective jammer location.
