Comparison between Sensors and Software and Malå GPR equipment based on test measurements at Bøaøyna, Stryn Municipality, Norway

Abstract

The aim of this report is to document the results of a comparative performance test between systems and antennas from two major GPR manufacturers namely Sensors & Software (S&S) from Canada and Malå from Sweden. The Malå RTA system utilizes a parallel endfire antenna configuration which facilitates measurements in rugged terrains as opposed to the bulky S&S perpendicular broadside mode equipment (PulseEKKO) which requires a relatively open terrain to operate. To carry out our tests, conversion of the S&S system to parallel endfire mode was required as well as measuring with Malå equipment on perpendicular broadside antenna configuration. Penetration depth and overall data quality was our main focus.
