| 摘 要： | 通过分析地面移动侦察系统对固定目标进行一次坐标测量时的测量过程,建立了固定目标坐标测量模型。通过对测量过程中误差传递规律的分析,导出了目标坐标测量误差的分布规律。根据坐标测量误差中各组成成分的大小,将测量误差分布规律近似成正态分布,并给出了分布参数的简化计算方法。仿真结果证实了误差分布规律近似及参数计算简化的可行性。

| Abstract: | A measuring model is built up in this paper after analyzing the one-time measuring process that the ground moveable scouting system measures a fixed target.The distributing rules of measuring errors of target coordinates are deduced by means of analyzing the transferring way of errors in measuring process and approximated to the normal distribution,of which a simplified calculating method for distribution parameters is presented,based on evaluating the components of measuring error.The approximation of error distribution rule and simplification of calculation on distribution parameters is confirmed by the result of simulation. |
