Interpretation of Raptor Data - Part 3 - Thick-slice Processing with OspreyView
Having covered several useful visualization and interpretation tools in previous notes, we have not yet talked about ‘thick-slice’ processing. Therefore, in this note, we present a novel method for visualizing 3D-GPR data more effectively by applying ‘thick-slice’ processing. To the best of our knowledge, this method has not been commercially available until now. The ...

Inspection of Internal Structure of Walls by Subsurface Radar
ABSTRACT This paper deals with the application of ultra-wide band time-domain subsurface radars, equipped with special signal processing techniques, to realize non-invasive image testing of the building walls' internal structure that are made with brick, stone, concrete, reinforced concrete and other construction materials. There are two normally associated problems, qualitative and quantitative, ...

Transmitter/Receiver Pulse-Driven Antenna Arrav with Near Field Beam-Forming for UWB Subsurface Imaging Radar
Abstract: The paper is devoted to design of impulse or equivalent ultra-wide baud array antenna for subsurface radar system. Receiving elements of this autenna are arranged in array with small physical aperture and polarimetric features. Two transmitting element support two polarization states for radiating signals. The radar antenna provides down-looking scanning in subsurface medium for small ...

Pavement thickness case study
Polk County, Florida A ground penetrating radar study was performed by GeoView to provide information on pavement thickness of a county road in central Florida. The study area was approximately 5 miles in length and was conducted in both lanes of traffic. The GPR data was collected using a proprietary road cart with a Mala Pro-Ex dual channel GPR system. Data was acquired simultaneously using ...

What is GPR?
Ground penetrating radar, or GPR, is the most modern and rapidly developing geophysical method. The possibilities of its application are being investigated, the number of tasks that it is capable of solving is increasing, and the equipment is being improved and modified. Today, GPR is used to investigate depths from the first centimeters (e.g. when monitoring the laying of runway surfaces) to ...

3D model evolution of a leak based on GPR image interpretation
This paper presents some aspects of the time propagation of underground water leakage in controlled laboratory conditions using a drilled polyvinyl chloride (PVC) pipe and interpreting ground penetrating radar (GPR) images. GPR pre-processed images are interpreted for easy identification and extraction of surfaces and volumes of water leakage. Finally, the temporal evolution of a water leak ...

An Inertial Measurement Unit Application for a GPR Tracking and Positioning
Abstract Abilities of an inertial measurement unit (IMU) for ground penetrating radar (GPR) tracking and positioning are presented at this paper. The IMU operation principle is based on calculating of the device's orientation in space via measurement of linear accelerations and angular velocities. Features of the IMU, GPS and wheel odometer are compared. Principal scheme of the IMU consisted of ...
