| 摘 要： | 为了提高基于地磁检测定向的精度,设计了一种新型的平面磁定向系统,该系统仅需要一个传感器的数据就可以确定磁方位。进行载体磁场补偿是磁定向系统实际应用的必要条件。结合新型磁定向系统的结构特点,基于椭圆拟合方法提出了一种新型智能误差补偿方法,推导出误差补偿公式。该方法不需要外界设备提供参考,仅通过定向系统本身的测试数据之间的相互关系就可以完成罗差补偿系数的求解。工程试验表明,该方法有着与传统给定基准法相当的补偿精度,却大大简化了操作,缩短了校准时间。

| Abstract: | In order to improve the accuracy,a new kind of plane direction finding system was designed.The system only needs one magnetic sensor to determine the magnetic azimuth.In practical application,compensation of the carrier's interference field is necessary.According to the principle of the new system,a new method based on ellipse fitting for compensating deviation is proposed and the formula is deduced.The method doesn't need other instrument.The whole compensation course is based on the interactive relation b... |
