摘　　要：在捷联惯导制导工具误差分离过程中引入交叉验证检验制导工具误差分离精度,并基于均方误差准则建立量化检验指标。首先建立简化的制导工具误差分离模型,并将数据划分成训练集和检验集;然后利用训练集进行制导工具误差分离;最后利用检验集和量化检验指标对分离效果进行检验。数学仿真表明,提出的误差分离模型正确可靠,精度较高,交叉验证能够对分离效果进行有效检验。The cross-validation is introduced into the separation method for guidance instrumentation error of strapdown navigation system, which can supply the absence of quantitative index to the testing progress. Firstly, a simplified separation model is established. Then the data set is separated into two sets known as the training set and the testing set. The training set is used to separate the guidance instrumentation error and test the separation effect with the testing set. The simulation data is proven that the separation model is credible and robust and the corss-validation can test the separation result effectively.
