摘　　要：对于2D机载雷达,由于缺乏准确的俯仰角信息,无法准确定位地面目标。针对该问题,给出了机载雷达目标定位的数学模型,分析了影响机载雷达目标定位的各种因素,计算了定位的几何精度因子(GDOP),通过仿真,得到了各误差因素综合影响下目标定位精度结果。目标定位精度分析为雷达系统设计,特别是雷达目标如何在数字地图下对目标进行准确定位提供了理论依据。A 2D airborne radar cannot locate the ground target precisely due to lacking of reliable elevation. This paper presents the mathematic model of target location, analyzes the factors influencing airborne radar location, computes the Geometric Dilution of Precision（GDOP） and obtains the result of target loca- tion precision affected by all the factors through simulation. Target location precision analysis provides theoretic foundation for radar system design especially how to locate the radar target on the digital map precisely.
