Processing Z gradiometer magnetic data using linear transforms and analytical signal

摘要: For 25 years the fluxgate gradiometer has been in common use magnetic archaeological prospecting. It constitutes a cheap and light solution well adapted for detection of earth-filled burned features elements built with brick or stones. Among different processing techniques that can be applied to data, we chose linear transforms, which aim at locating delineating precisely buried correcting field inclination using no priori information about causative bodies. We these transforms ΔZ by calculation spectral domain both synthetic measured data. The advantages this application depend on characteristics searched their environment, several transformed maps calculated interpreter order choose most convenient given survey. © 1997 John Wiley & Sons, Ltd.
