High-amplitude, short-wavelength culture-related magnetic anomalies can adversely impact the processing and interpretation of aeromagnetic surveys. Since cultural features (man-made objects) are surface or near-surface, the problem is especially acute for modern HRAM (high resolution) surveys flown with low terrain clearance and close line spacing. Because of the low terrain clearance, the sensor-source separation is relatively short and the signal fall-off (inverse square or inverse cube) [...]
