📡 Land-Survey Geophysics Field Lab: Metal Detector Eddy Currents, GPR Radargram Hyperbolas and Depth-Slice Maps

3D test field with a survey rover: see how an induction-balance metal detector and ground-penetrating radar detect buried inanimate objects. Eddy currents, 1/z^6 depth law, soil mineralisation, radar velocity, reflection coefficient, hyperbola depth calibration, depth-slice maps and detection probability.

⚙ Under the hood

Drive a survey rover over a 3D grass test field with buried inanimate objects: an induction-balance metal detector (eddy currents, 1/z^6 depth law, ground balance in mineralised soil) and ground-penetrating radar (v = c/sqrt(er), reflection coefficient, radargram hyperbolas, depth calibration) build a depth-slice map line by line, with detection probability versus depth, guided lessons and a sandbox.
