In June 23rd 2015, NGU conducted a set of GPR test measurements in Eikesdal, Møre og Romsdal county. The aim for these measurements was to compare performance of the NGU georadar systems. A single profile was measured four times i.e. with two different GPR systems (PulseEKKO PRO and Malå RTA) and two different antennas (50 and 100 MHz) per system. All profiles were measured using similar time window (~2000 ns) and sampling frequency (~10x antenna frequency) settings albeit with different antenna configurations: PulseEKKO uses perpendicular broadside antenna configuration as opposed to Malå RTA which utilizes parallel endfire by default. The 800-meter long profile was measured on a country road alongside Aura river and displays a delta succession with topsets, foresets and bottomsets. The pronounced foresets are inclined towards the Eikesdalsvatnet lake to the north.
