Abstract :
Practical GPR survey schemes based on a geometrical migration algorithm are implemented and experimentally tested: (1) random GPR data collection from water surface along a tangled path and interpolation to a regular grid for bottom reconstruction; (2) double-pass B-scan with different antenna offset for estimation of the upper ground layer thickness and permittivity. An analytical relation between the shape of subsurface reflecting interface with measured signal travel times is used for the reconstruction of the layer parameters.
