摘要
针对大多光电经纬仪不具备单独定位能力、测角交会方法受布站局限的缺陷,引入脉冲雷达测量元素信息,提出了光雷联测融合定位算法,根据布站几何关系确定光电经纬仪的等效距离,结合其测角信息实现定位功能。计算结果表明,光雷联测融合定位算法计算的位置坐标结果与雷达单台定位相差不足30m,而精度明显优于雷达定位精度,与光电经纬仪定位指标精度相当。光雷联测融合定位算法开拓了外弹道数据的处理途径,有效提高了弹道精度。
For eliminating the limitations such as no single-location capacity of most photo-electric theodolites, and the restriction of station distribution due to using angular intersected method, radar tracking elements were induced and the fusion location algorithm of theodolites and radar associated measurement（TRAM） was put forward. According to the station distribution geometry, the equivalent range, which can locate singly associated with the angular of photo-electric theodolites, was determined. The computing results show that the difference in three directions by using two methods is not more than 30m. The precision determined by above-mentioned method, which corresponds to the location standard precision of photo-electric theodolites, is obviously superior. The fusion location algorithm of theodolites and radar associated measurement extends the way to data processing of exterior ballistic measurement and effectively improves the precision of trajectory.
