摘　　要：在光电经纬仪伺服系统动态性能室内检测过程中,利用动态靶标产生类似雷达引导信息的实时引导数据来对光电经纬仪的外引导性能进行检测,同时为动态性能、捕获能力等指标的室内检测提供新的方法;引导数据通过对动态靶标的目标编码器值坐标变换产生,同时为消除数据采集、处理、传输带来的滞后,采用有限记忆最小平方预测法对数据进行预测处理并对预测精度做了仿真、实验;引导数据以异步串行通讯的方式发送给光电经纬仪,完成对光电经纬仪的外引导。The reahime guidance data which is produced by dynamic target is provided for testing external lead function of photoelectric theodolite, according to the need of indoor checking and testing of the dynamic characteristic of theodolite＇s tracking system. It＇s also a new way of testing the theodolite＇s dynamic characteristic and the ability of capturing target. The guidance data is gained through encoder number＇s coordinate transformation. In order to avoiding the time delay of data＇s collection, transaction and transmission, the guidance data is predicted based on the theory of fixed--memory least squares prediction filter. The simulation is carried out to analyse the precision of predic tion. The guidance data is transmitted to the theodolite in the mode of asynchronous serial coommuication.
