The GSSI Academy provides an overview of RADAN® 7 packages and modules to post-process GPR data. This post also provides instructions on how to activate your RADAN 7 software.
RADAN® is GSSI’s post-processing software for ground penetrating radar (GPR). Short for Radar Data Analyzer, RADAN was first developed by GSSI in 1984 and released in 1987 to post-process GPR data. This software allows users to select the processing functions that best suits their needs. RADAN is Windows™ based, which provides a familiar and easy-to-use environment for all levels of user experience. In 1994, RADAN changed from a disk operating system (DOS) to Windows.
RADAN 7 Software Options
There are three types of software packages for RADAN 7. RADAN 7 Main is the primary platform for all GPR applications. Users have the ability to customize their RADAN 7 software with additional modules:
3D: The 3D Module allows the user to view and build 3D visualizations. This module helps interpret and annotate complex subsurface structures and is often used to create report graphics.
RoadScan™: The RoadScan Module is used to analyze pavement, base, and sub-base layers in roadways.
BridgeScan™: The BridgeScan Module allows users to process bridge deck GPR data and account for skew angles. Features included aids users to map bridge deck deterioration and export data in multiple file formats, such as .kml and excel.
GSSI also offers two versions of RADAN that are application specific for the concrete inspection and utility locating markets. These packages are separate from RADAN 7 Main and cannot be upgraded.
RADAN 7 for StructureScan™ Mini is designed to process, view and document 2D and 3D data collected with the StructureScan Mini series systems.
RADAN 7 for UtilityScan® is designed to process, view and document 2D and 3D data collected with our UtilityScan product line.
How to Activate RADAN 7
When users purchase RADAN 7, they are provided a unique digital product key and serial number that is needed to install the software on their computer. RADAN 7 will automatically activate purchased modules when the activation codes are input. If one does not input the activation codes, the software will go into Demo Mode for 30 days or 33 uses, whichever comes first. After which, the software defaults to a RADAN Reader version.
When importing your GPR data into RADAN, you will see different files depending on the systems you collected the data on. Below we’ll list out the types of file names and differences between them.
Setting up a Source Directory
Lastly, users should know how to generate and set up a source directory in RADAN before beginning any processing. The source directory tells the RADAN program where to look for the data for processing.
When opening the software, click on the global settings option, which will open a pane on the right side of the screen. Upon double clicking on the word source directory, a file browser will open allowing users to browse the location containing the data for processing. Once this source directory is set to the correct location, clicking “Home > Open” will open that source directory right away.
Note: If “Autosave files” is set to Yes when setting up the source directory, RADAN will automatically save files in the source directory in a folder called “PROC,” short for processed files. Alternatively, “Autosave files” can be set to No, which gives users the ability to rename files as they’re being created.
