摘要
中高山地区地形复杂,飞行高度较高,航磁测量获得的磁异常强度相对弱小。为了更有效地利用高精度航空磁法测量得到的磁异常信息,在充分论证中高山区弱磁异常存在的可靠性基础上,结合中高山地区特点,提出了改进的非线性滤波方法,并给出其实际应用效果。
In middle and high mountain areas, the landform is complex, the flying altitude should be relatively high, and the intensity of magnetic anomalies detected by aeromagnetic survey is hence relatively weak. In order to utilize the magnetic anomaly information obtained by high-precision aeromagnetic survey more effectively, this paper, based on the reliable proof of the existence of weak magnetic anomalies in middle and high mountain areas and combined with characteristics of middle and high mountain areas, has advanced an improved nonlinear filtering method and described its effect in practical application.
