摘要:
针对目前大量常规弹药低成本姿态测试的需求,微惯性传感器存在的漂移特性不能提供长时间稳定姿态角的问题,本文提出了利用三正交磁传感器的积分比值姿态测试方法。推导了磁传感器输出信号之间的积分比值与弹体俯仰角的理论公式,采用多点的统计特征比值代替单点特征比值。对积分比值法进行了适用性分析,分析了积分误差及偏航角误差造成的俯仰角查表误差;通过仿真对比分析,在低信噪比情况下,积分比值法比三正交比值法的解算精度高了5倍左右。半实物实验结果表明:积分比值法的姿态角解算误差在±0.6°以内。该姿态解算方法抗干扰能力强,数据利用率和姿态解算精度高,是一种简单有效的弹体测姿方法,能够满足旋转弹体的姿态测试要求。
