A Intersection Research of Radar and Electro-optic Theodolite Based on Space Geometry

雷达-光电经纬仪联合定位方法是一种全新的现代靶场测量技术,在光电经纬仪附近部署雷达,雷达测距,光电经纬仪测角,通过将两者交会测量的数据融合,从而可以实现对目标的定位;将目前通用的数学定位模型进一步转换为空间几何定位模型,该模型能够更直观地描述目标在空中某一位置时各测量参数之间的关系,能够准确地体现出该时刻各设备的有效探测范围。结果表明,在距设备为5km的探测范围内对目标的定位精度较高;该方法同时提高了计算效率,为实现计算机虚拟仿真提供可靠的依据。

The joint positioning method of radar and electro-- optic theodolite is a new measuring technique in modern shooting range, dc ploying a radar near the electro--optic theodolite, data fusion will be implemented by using the angle-measurement information obtained from theodolite and the range finding information from adiacent radars, as a result, the spatial position of the target can be determined; it can describe intuitively the interrelationship of measuring parameters by further convert the universal model based on mathematic positioning into a positioning model based on space geometry, when the target is moving at a position in the spatial, the equipments＇ detection range can also be embodied precisely. The result shows that the positioning accuracy of target is higher in the 5 km range of the equipments. At the saint＇ time, this algorithm will be more efficient and provides reliable foundation for computer virtual simulation.
