| 摘 要： | 导航载体上电气设备产生的电磁噪声是影响地磁测量精度的主要因素之一。针对电路设备产生的磁场噪声,提出了采用EMD-形态滤波降噪算法,较好地消除了高频交变和脉冲类磁场噪声;针对载体上多种电气设备产生的综合磁场噪声,论文采用上述提出的EMD-形态滤波降噪方法进行了降噪处理,有效地抑制了载体多种电气设备产生的交变磁场噪声及其中包含的脉冲类噪声,提高了地磁测量的精度。

| Abstract: | Electromagnetic noising that produced by the electric equipment on a navigation carrier is a main causation which influenced the geomagnetic measurement precision.The article put forward EMD-shape filter aim at the yawp made by circuit equipment,Preferably banished yawp of high frequency change and impulse.Aim at multi-magnetic yawp engenderd by the carrier adopt the way of EMD-shape filter to drop.Test proved that this method is effective for the yawp made by circuit equipment,and improved the geomagnetic measurement precision. |
