火箭飞行鉴定模拟器基准误差传递分析

The error transfer's analysis of measure criterion on a rocket-flight appraisal simulator

根据单脉冲雷达及其它火箭飞行地面测控设备精度鉴定的需要 ,推导出单台和两台激光电影经纬仪基准在火箭飞行鉴定模拟器航路上的设备固有误差传递变化关系式 ,从而决定 :1.基准是否可用 ?2 .在两台经纬仪都有数据的情况下 ,何时用交汇基准、何时用单台基准才能使鉴定更准确 ?3 .怎样才能鉴定速度 ?本文推导出了公式 ,给出了便捷的计算方法和误差传递上机计算曲线 ,并进行了分析。模型已成功地应用于单脉冲雷达的精度鉴定 。

on the basis of the accuracy evaluation's demand of single impulse radar and other ground measure equipment,model of the inherent error transfer of one or two laser ballistic camera as comparison criterion on fairway of a Rocket Flight Appraisal simulator are worked out.three respects analysis follows:(1)Will the criterion be able to be used?(2)In cases of two laser ballistic camera having effective data,where does the one ballistic camera be as criterion?where does the two ballistic camera be as criterion?(3)How can the speed be evaluated?The formula,calculation method's simplification as well as the curve figure of the error transfer of the criterion are given and analysed.The model has been successfully used in single impulse radar's accuracy evaluation.it is a typical case of the error analysis.
