摘　　要：研究用经纬仪测定运动目标位置过程中的有关问题。为保证算法的实时性 ,采用直线插值方法。根据非整数倍周期时的偏差量 ,给出偏差量在整数倍周期时的带有延时作为参数的表示式。利用这一表示式 ,在目标作匀加速运动的前提下提出了延时的辨识方法 ,从而解决了目标位置合成中的难题。The related problems concerned in the process of determining the moving target position with a theodolite are studied. In order to maintain the timeliness of the algorithm, a linear interpolation is applied to the paper. An expression with time-delay as parameter is given when the deviations are within the period of the integer multiple according to the deviations in azimuth and elevation angles during the period of non-integer multiple. With this expression, an identification method for time-delay is proposed on the premise of even acceleration moving target, thus the difficult problems in the synthesis of target position are solved.
