【摘要】针对基于最佳椭圆拟合的磁罗盘误差补偿算法，设计了一组模拟不同类型干扰磁场的数据采集与罗差分析实验。通过对磁罗盘在各种干扰磁场下表征测量数据特性的拟合椭圆参数与最终补偿效果的详细分析，对理论公式进行了比照与补充，同时探讨了软铁干扰磁场与硬铁干扰磁场的相互作用关系以及在综合磁航向误差中各自所产生的影响。关 键 词 磁罗盘; 罗差; 最佳椭圆拟合; 误差补偿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.
