靶场光电经纬仪测量数据的误差分析及数据处理

Error analysis and data process of electro-optical theodolite in Proving Ground

光电经纬仪是在现代靶场测量中广泛应用的一种测量仪器,但是光电经纬仪在跟踪飞行目标的过程中,会因各种原因产生测角误差,影响弹道的测量精度。采用卡尔曼滤波的方法可以对光测数据进行有效的处理,提高其测量精度。本文通过对光电经纬仪测量数据的误差分析,建立了误差模型,并对测量数据进行了卡尔曼滤波,生成滤波数据弹道曲线。从而得到较为准确完整的弹道测试数据和外推数据,提高弹道数据获取的精度,最大限度地延伸弹道测量设备跟踪距离。

Electro-optical theodolite is a measuring instrument broadly used in the range measurement. Since electro-optical theodolite would trigger measure errors and influence the measure precision of trajectory when tracking the flight targets, we use kalman filter to effectively process the data, which would improve the measure precision. This paper analyses the measure errors of electro-optical theodolite, build up the errors model, process these data with kalman filter, and create trajectory curve in corresponding with filter data. By this way, we can achieve exact trajectory measure data and extrapolation data, which will improve data measure precision and extend the track distance of measure facilities.
