OKM Gepard GPR - Ground Penetrating Radar

Features

The Gepard GPR is a very flexible and powerful Ground Penetrating Radar for the detection of underground objects like pipelines, cavities, cables, conduits, tunnels, bunkers and foundations.

The Gepard ground penetrating radar uses an omnidirectional unshielded transmission system to reach maximum depths up to 40 meters (131 ft). The agile and compact unit can easily be operated by a single user via Android Tablet PC.

The RADAR (Radio Detection and Ranging) of the Gepard GPR 3D sends a signal into the ground and awaits the reflection or echo of the signal to detect sub-surface anomalies.

Detectable Objects and Structures

• underground walls, basements and concrete reinforcements
• hidden cavities, graves and sepulchers
• water level and underground rivers and aquifers
• buried pipelines, conduits and cable harnesses
• backfilled wells, galleries, trenches and dugouts
• septic tanks, distribution boxes and drainage pipes
• secret tunnels, bunkers and shelters
• buried treasure chests, statues and caches

Optimization of Ground Surveys

The Gepard ground penetrating radar is using a multiple transmission frequency range starting at 60 MHz up to 300 MHz which is realized by adjustable telescopic antennas. It furthermore supports many automatic adjustments to optimize your ground surveys on specific soil types, which makes the handling of the Gepard ground radar very easy. You just set your depth resolution and start surveying.

Measurement Data Analysis with Android App

The measured data of the ground penetrating radar is immediately transferred to the Android Tablet PC. The Android software receives the data via WiFi and displays it directly on screen.

The software offers the option of integrating a GPS signal or Google Maps, filtering automatically and entering notes for later recollection of specific scan details. Additionally, the automatic filtering option improves the results of your scan and assists in finding hidden objects and structures more easily. Due to the integrated GPS all scan positions can be stored along with the scan data.

GPR Scan Analysis

The new render views in OKM's 3D software Visualizer 3D Studio allow visualizing detected structures for more detailed analyses.

As soon as you open a GPR measurement, the Main Toolbar will include a further button. Here you can switch between the 2D and 3D render view.

Improve the scan image e.g. by selecting one of the newly added OKM GPR Soil Types (Right Sidebar) and configuring the Visualization (Right Sidebar), e.g. select Smoothing.

In the Visualization menu (Right Sidebar), you can change the Threshold to regulate the number of hidden/visible scan values and corresponding colors for the Volumetric render view.

This will help you focus on the most significant targets in your scan image.
