By synthesizing twice MTD results, actual velocity of the target is gained. Relation between pulse duty ratio and velocity measurement error is deduced.
综合两次MTD结果得到了目标的实际速度,并推导出了脉冲占空比和速度测量误差的关系式。
It includes system design, manufacture of key parts (absorbing target and reflecting target), actual measurement and error analysis of the whole system.
主要包括系统设计、关键部分(吸收靶、反射靶)的设计制作、实际测量以及整体的误差分析。
On the basis oft-distribution theory, this paper gives the method of judging system error with t-inspection criterion. This judging method is more suitable for the actual measurement situation.
本文基于t分布理论,给出了用t检验准则来判断系统误差的方法,这是一种更符合实际测量情况的判断方法。
