unaccuracy造句

• The tactical missile seeker handover accuracy from midcourse to terminal guidance is researched . the small perturbation method is proposed to analyse error sensitivity of the seeker presetting parameters from error sources . firstly, the terminal guidance seeker presetting parameters are computed, based on the equations of a surface-to-air missile movement and a target movement . then the seeker presetting unaccuracy due to the command guidance radar measurement errors is also computed . it can be seen that the seeker presetting errors increase rapidly when the missile is close to the target, which leads to an important conclusion that the late seeker handover from midcourse to teminal guidance should be avoided
  研究复合制导的战术导弹中末制导交班的导引头预定精度问题.提出用小扰动法分析导引头预定参数对误差源的误差敏感性关系.以中远程防空导弹为例，结合导弹运动方程组和目标运动模型，计算了中末制导交班的导引头预定参数，并计算了在制导站雷达测量误差下的末制导导引头预定参数的计算精度.可知，导引头定位参数的计算误差随着弹目距离的接近而显著增大，得到中末制导交班不能太晚的重要结论
