摘　　要：研究了机载单ESM传感器对运动目标的定位问题.建立了单ESM传感器平台作航向机动时对运动目标定位的数学模型以及相应的求解方法,克服了单ESM传感器平台做直线运动时对运动目标观测存在不可观测的局限性,对于ESM平台作航向机动和匀速直线运动情况具有普遍适用性.理论分析和仿真结果表明:文中提出的算法,能够迅速有效地对运动目标进行定位,并具有较高的定位和跟踪精度,航向机动量越大,对目标的定位精度越高.Single ESM sensor tracking a moving target is studied in this paper. The model of single ESM sensor on a maneuvering platform tracking a moving target is set up, and the solution to the model is deduced in detail. The algorithm is applicable to all cases, which overcomes the limit of observability when the platform moving in the mode of constant velocity movement. The theoretical analysis and simulation show that the algorithm presented in this paper is able to position the moving target rapidly and effectively, with higher positioning accuracy,
