摘要
采用双因素等重复试验方差分析(ANOVA)方法实现对惯性测量组合的电磁敏感度试验评定。将惯性测量组合(IMU)参数标定测试与电磁敏感度试验相结合,克服了单独进行电磁敏感度试验难以区分评定等级的难题,从而获得参数标定位置因素与电磁干扰强度因素对惯性测量组合输出脉冲个数的单独影响和交互作用。
Two-way analysis of variance （ANOVA） for balanced repetitive test is utilized to experimentally evaluate the susceptibility of the inertial measurement unit （IMU） to electromagnetic interference （EMI）. The issue of how to match the experimental evaluation level of the electromagnetic susceptibility limits is brought to a close by means of combining the electromagnetic susceptibility test with the parameters calibration of IMU. The single predictor effect of EMI and of parameters calibration angles respectively on the number of output impulses from IMU is assessed as well as the interaction of the two predictors.
