火箭飞行精度鉴定基准误差传递建模与分析

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，建立激光电影经纬仪基准在火箭飞行精度鉴定航路上的误差传递数学模型，从而决定：1）基准是否可用？2）在2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？给出了数学模型、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，作为误差分析的一类典型应用。

Error Transfer's Analysis about Evaluation Criterion of a Rocket-Flight

On the basis of the accuracy evaluation's demand of single impulse radar and other ground measure equipment, model of the inherent accuracy of ballistic camera as Evaluation's comparison criterion on fairway of a Rocket-Flight are worked out. Three respects analysis follows:1) Will the criterion be able to be used? 2) In case 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 have been successfully used in single impulse radar's accuracy evaluation. It is a typical case of the accuracy analysis.
