摘要
使用磁场波数域正则化化极方法，对干扰严重的中低纬度航磁异常数据化极，能压制磁南北向的条带状干扰，获得稳定结果；对含有较高噪声水平的高精度地面磁测ΔＴ异常化极，不论纬度高低，都能较大程度地压低噪声水平，获得高质量的化极结果。
Regularizing reduction to the pole of the aeromagnetic data with strong interference at low-medium latitudes may inhibit the banded interference in magnetic south-north direction and gain stable results by regularizing reduction to the pole of magnetic field in the wavenumber domain. Regularizing reduction to the pole of higher-noise-level and high-accuracy ground magnetic ΔT data, with the independence from latitudes, may decrease noise-level to a great extent and gain better results of reduction to the pole.
