【摘要】 针对运载火箭测量数据中出现测量信息序列出现野值的问题,提出了在火箭飞行测量的数据实时处理中使用测元野值剔除技术,对运载火箭的测量数据进行处理,并在同一时刻存在多个测量信息源序列的情况下,选取可用的测量数据源,利用所建立的野值剔除模型对不同数量数据源的测元数据进行处理,消除弹道处理实时计算中不可信的异常跳动点问题,通过火箭飞行任务的弹道数据验证算法的正确性和有效性,该方法应用在运载火箭弹道测量数据的实时处理中,对获得火箭飞行的平滑弹道具有很好的效果。更多还原

【Abstract】 In view of the outlier in measurement information sequence of the rocket measurement data, this paper proposes the technique of the elimination outlier in real-time measurement data processing of rocket flight. In the case of multiple sources of measurement information at the same time, the available measurement data source is selected and the source data of different data source are processed with establishing outlier elimination model to eliminate the unbelievable abnormal pulsation pointsin the real time trajectory calculation. The correctness and effectiveness of the algorithm are verified by the trajectory data of the rocket flight task. This method is applied to process real-time trajectory data of rocket, and has a good effect on the trajectory of rocket flight.更多还原
