摘　　要：一台经纬仪只能测量目标的方位角和俯仰角,即只能测得目标的方向。为确定空间运动目标在某一瞬间的位置,采用两台(或多台)经纬仪合理布站进行交汇测量的方法,可得到目标点的坐标值,根据不同时刻的坐标值,用最小二乘法对目标航迹进行曲线拟合,从而可以外推预测目标下一时刻的位置、速度和加速度。A theodolite can only be used to measure azimuth angle and elevation angle of a target, i.e. direction of a target. In order to determine the simultaneous position of a target moving in space, the coordinate values of a point target can be obtained by means of the intersection measurement carried out with two sets (or multiple sets) of theodolite reasonably allocated in measuring stations. The position, speed and acceleration of a target at the next moment can be predicted through target track curve fitting with the method of least square according to the coordinate values at the different moments.
