基于随机加权法的捷联惯组历次测试数据总体参数验前分布研究

The Population Parameter Prior Distribution Study of Successive Test Data of SIMU Based on Random Weighting Method

针对捷联惯性测量组合(捷联惯组)历次测试数据小样本的特点,在总体参数分布形式未知的情况下,根据已有的先验信息,提出了通过随机加权法,获得捷联惯组历次测试数据总体参数的验前分布,可以减小小样本情况下的统计分析误差.

Aiming at the small sample of successive test data of strapdown inertial measurement unit （ SIMU）, random weighting method is used to get the prior distribution of population parameter of successive test data of SIMU with prior information, when the distribution form of population parameter is unknown. It can reduce the error of statistical analysis in the case of small sample.
