在反舰导弹靶场试验时，导弹的飞行高度可由弹上无线电高度表测量，通过遥测设备获得导弹高程，研究了利用导弹高程数据经坐标转换计算导弹斜距，实现机载红外经纬仪对导弹单站定位的方法；分析了机载红外经纬仪站点与导弹的高程差和斜距值对单站定位精度的影响，用蒙特卡罗法仿真估算了机载红外经纬仪单站定位与两台机载红外经纬仪交会定位的精度，仿真计算结果显示对于斜距在数千米的海面低空飞行的反舰导弹，单站定位精度与两站交会定位精度相当，单站定位用于导弹脱靶量测量的精度高于导弹定位精度一倍以上。

In the range test of anti-ship missile,the missile’s flight height can be obtained by telemetry equipment on the missile.This elevation data are be used to calculate missile geodesic distance by coordinate transformation,and the positioning method of airborne infrared theodolite single station is realized.The influence of the difference in elevation and geodesic distance of airborne infrared theodolite station and missile on single station positioning accuracy is ana-lyzed,and single station positioning accuracy of airborne infrared theodolite and intersection positioning accuracy of two airborne infrared theodolites are estimated by Monte Carlo simulation.The simulation results show that for sea low altitude anti-ship missiles with the geodesic distance of several thousand meters,single station positioning accuracy and two-station intersection positioning accuracy are of same level.And single station positioning accuracy for missile missing distance measurement is more than one times higher than that of missile positioning.
