在**系统飞行试验中,一般使用光学测量、雷达测量、光电测量等手段获取弹道参数。为了进一步提高测量精度,提出了光电经纬仪在测量过程中同步探测目标和短波红外星体的思路,从多通道组合探测、短波红外测星能力、光电经纬仪布站规则等方面对高精度在线星校技术进行可行性论证,并分析在线星校能修正的误差项。理论分析结果表明：在线星校修正精度优于10″，满足靶场测量精度要求。

Optical, radar or optoelectronic measurements are used to obtain ballistic parameters in weapon system flight trials. In order to further improve the accuracy of measurement, a new idea based on detecting target and SWIR star at the same time is brought forward. The feasibility demonstration of high-precision online star calibration technology is carried out with analysis of multichannel combinatorial detection, SWIR star measuring ability and rules of distribution of photoeletric theodolite. The measuring errors which can be calibrated by online star calibration are analyzed. Theoretical analysis results show that the precision of online star calibration is better than 10″,which meets the accuracy requirement of target range.
