GPR Data Examples
UTILITY MAPPING WITH RADARMAP SOFTWARE
RadarMap software is designed for real-time underground utility detection and mapping. Fully touchable easy-to-use user-friendly interface allows to mark all found utilities by different label types, chained between map and georadar profile, with single touch. Software supports multi-layer maps and automatically marking utility position based on the utility layer information.

DETECTION OF REBARS
Detection of rebars in concrete floor in Radar Systems, Inc. office. June, 2014. Improved 1.5 GHz shielded antenna was used.
SOUNDING OF ASPHALT PAVEMENT
Sounding of asphalt pavement on the Darzciema street, Riga, Latvia. June, 2014. 1.0 GHz air launched shielded antenna was used.
DETECTION OF THREE OIL PIPES
Detection of three metal pipes buried in soil to the depth of 1.0 to 1.5 m. Each pipe generates a path signal having a hyperbolic shape whose apex corresponds to the pipe location. Sounding frequency: 900 MHz. Location area: vicinity of Daugavpils, Latvia.
DETECTION OF A KARST CAVITY
Detection of a karst cavity in limestone below a loamy layer. The cavity (enclosed in a circle) is seen as alternating strips in the left-hand part of the profile. Loam is displayed as a continuous signal in the upper part of the profile. Sounding frequency: 300 MHz. Location area: Dead Sea beach, Israel.
PROFILING OF AN ANCIENT RIVER BED
Profiling of an ancient river bed which is not seen through on the present-day profile. River bed signals are in the left-hand part of the profile. Signals from various lithological boundaries are seen in the upper part of the profile. Sounding frequency: 300 MHz. Location area: vicinity of Shventoy town, Lithuania.
SOUNDING A DRIFT WALL IN A SALT MINE
This profile was obtained by sounding a drift wall in a salt mine. Well visible signals have a shape of multiple hyperbolas originating from an adjacent drift. Distance between the two drifts is approximately 7.5 m. Sounding frequency: 500 MHz. Location area: Mirny, Russia.
SOUNDING OF A BRICK WALL
Sounding of a brick wall. Mid-part of the profile clearly shows a signal from an built-in metal cabinet. Sounding frequency: 2 GHz. Location area: Riga, Latvia.
PROFILING OF A SANDY HILL
Profiling of a sandy hill. Movement of a georadar was from the foot of the hill (left) to its top (right). Therefore, signals from the grown water table and various boundaries are drifting down. A major nonuniformity is recorded almost at the top of the hill, at the depth of 35 m. Sounding frequency: 38 MHz. Location area: vicinity of Lilaste lake, Latvia.
PROFILING OF A LAKE
Profiling of a lake from the bottom of plastic boat. Shielded antenna 500 MHz was used. There are several metalic objects very well visible in silt layer.
