Selection of Adaptive Area in Geomagnetic Navigation Based on the Principal Component Analysis
摘要
Abstract
The greater the magnetic field information, the better the navigation performance. By introducing the concept of mathematical statistics and information theory, a number of criterions to evaluate the characteristics of geomagnetic infor-mation were established. Then by the principal component analysis, the relevant criterions were excluded, and the integrat-ed index was obtained. So the navigation performance of adaptive region was analyzed objectively and quantitatively. Ac-cording to the analysis, the best navigation adaptive area could be chosen. The simulation results showed that there were richer navigation information and better performance in select adaptive area.关键词
