【摘要】針對基于最佳橢圓擬合的磁羅盤誤差補償算法，設計了一組模擬不同類型干擾磁場的數據采集與羅差分析實驗。通過對磁羅盤在各種干擾磁場下表征測量數據特性的擬合橢圓參數與最終補償效果的詳細分析，對理論公式進行了比照與補充，同時探討了軟鐵干擾磁場與硬鐵干擾磁場的相互作用關系以及在綜合磁航向誤差中各自所產生的影響。

In this paper, a set of data collection and magnetic deviation analysis experiments which can simulate different magnetic disturbances are designed based on ellipse-specific fitting error compensation method. Under the condition of diverse magnetic disturbances, ellipse parameter which depict measured data characteristic and the last compensation effect are analyzed in detail. Theoretics expressions are compared and complemented with experiment results. At the same time, the interaction of soft iron and hard iron distortion and the role of each in the whole magnetic heading error are discussed.
