在数据处理的应用领域 ,观测数据对系统参数估计提供了多少信息量是一个令人关心的问题 .基于共轭正态分布 ,利用统计推断的结论 ,研究了相关的观测样本可以提供多少统计信息的问题 .此结论可应用到航天测控领域中的试验鉴定中 .可以充分利用制导工具误差造成的弹道主动段的遥外弹道差数据 ,借助折合算法 ,将弹道差数据转换为关机点数据 .再通过关机点和落点偏差的关系得到相应的落点偏差 ,通过度量相关观测点提供的Fisher信息量作为权重 ,融合这些落点偏差信息 ,可对导弹进行更全面的鉴定
In the area of data processing, how much information is provided by observational data on system parameter estimation is a concern.According to the conclusion of statistical inference based on the conjugate normal distribution, we study how much statistical information can be provided by relevant observation samples This conclusion can be used in the field of space flight test and control in the field of test identification.Full use of guidance tool error caused by the ballistic projectile remote trajectory difference data, with the reduction algorithm, the trajectory difference data is converted to the shutdown point data. Through the relationship between off-point and landing-point deviation, the corresponding landing-point deviation is obtained. By measuring the Fisher information amount provided by the relevant observation points as a weight, the missile can be more comprehensively identified by integrating these landing-departure information
