高维情况下双差整周模糊度LAMBDA法解算分析
Analysis of a double-differ ambiguity solution by the LAMBDA method in high dimensional application
摘要
Abstract
Invalidation problems of the least-squares ambiguity deeorrelation adjustment ( LAMBDA) method in high dimensional applications such as the model of multi-baselines and networks were researched. Based on the expatia-tion of the process of LAMBDA deeorrelation, a problem relating to decomposition and ordering of the matrix was analyzed using the matrix analysis method. Also, the incomplete ordering of conditional variances after the decore-lation of high dimensional ambiguity was noted. Furthermore, the descending order of conditional variances was theoretically shown to be the premise of ambiguity valid solutions. The conclusion was drawn that the reason for the disabled LAMBDA deeorrelation was that the descending management of conditional variances was faulty.关键词
