弹道摄影测量站间时间不同步量计算方法

An Algorithm for the Asynchronous Time between Two Trajectory-tracking Photographic Measurement Stations

弹道摄影测量中,有时出现两个观测站的测量数据时间不同步的现象,此时数据不能用于正常处理。对此,给出了计算时间不同步量的方法,使数据经时间不同步误差修正后可用;数据仿真表明,该方法计算时间不同步量的精确程度高,结果稳健,适用范围广,可应用于靶场测角体制下数据时间不同步的事后处理。

During trajectory- tracking photographic measurement, on occasion comes forth the problem that the tracking stations＇time is asynchronous, so the data cant be put into usual processing. An algorithm for the asynchronous time is presented and then the mended data can be usually utilized. The emulation data show the algorithm gives more precision and more stable results for more wide scope. It can be applied to range post -flight angle -only data processing.
