K2 FastWave - Acquisition Software for use in the Field



Software is the acquisition software designed to work with the IDS DAD FastWave control unit (single or multi-channel) and is included in the DAD package. The K2 FastWave is able to support the acquisition of up to 8 antennas connected in chain and is able to show two radargrams simultaneously on the screen in real time during the acquisition phase.

The software comes with comprehensive tools to customize the acquisition parameters and calibrate the signal of every acquisition channel.

From the initial interface the operator can estimate the propagation velocity as well as modify many other parameters.K2 FastWave is also able to continuously monitor the status of the system, providing an alarm for every possible malfunction that can happen in the field.K2 FastWave also has a dedicated tool to help the user collect data in grid mode in order to achieve the best results from the survey, mixing longitudinal and transversal scans in the post processing. The system can be connected to GPS and is able to record the path in real time and mark anomalies: the data is stored in a dedicated folder and is easy to access in the future post processing phase.

Post Processing Software

The GRED Post processing software family is modular. Every module includes the capability of the software listed above.

GRED Basic - Recommended for generic basic post processing analysis and road pavement evaluation



GRED is an easy to use post processing software able to post process the data acquired with the IDS K2 FastWave. The software offers general tools and features and can be used for several applications from geology and archaeology to underground utility detection. This software is equipped with basic features and is recommended for users that have to analyze data in the office and want to maximize their capability of interpretation. With this software the user will be able to process in 2D the radargram acquired in the field.

The software is able to show the B-Scan (radargram) acquired and to apply several types of filters (background removal, gain, mitigation time domain, etc.) to obtain an easier to interpret B-Scan. It is also possible to set filter macros for iterative filtering of the data. Anomalies as well as pipes can be marked directly on the interface. GRED Basic is also able to do semi-automatic layering reconstruction and insert core.

GRED 3D - An Advanced GPR Processing and Imaging Software Recommended for pipe and utility mapping and 3D analysis of the subsurface



is an advanced post processing software for 3D and tomographic rendering of the acquired data. The software is able to present a 3-dimensional view of the subsurface, with a complete set of options for navigate within it, cutting it and marking anomalies. The software is also able to export 2D plan-view slices of the subsurface from which the operator can best interpret anomalies and pipes. The pipes and cables detected can be marked with a dedicated tool where the operator can specify a color for each pipe, the depth of it and an estimate of the dimensions. The marked pipes can then be visible in the 3D view, the 2D tomography slice and the traditional radargram. The software is also able to show multiple radargrams simultaneously to enhance the capability of the interpretation.




GRED 3D CAD for Windows XP is an industrial software dedicated to processing RIS data and generating cartographic output. The environment has been designed to provide highly interactive and efficient management of the large quantity of data acquired by the RIS Acquisition Unit. The 2 monitor configuration permits you to view radargrams as multiple sections (standard representation) together with the tomographic view. Results of the data analysis can be transferred to CAD either using an interactive link or at the end of the work session. In the latter case, GEO MAP automatically generates the final cartographic output.

The innovative functions allow a reduction in the human factor in the radar data interpretation with a drastic reduction in the data processing time.
The main benefits and features are:

  • Dramatic reduction of processing time, by more than 60%
  • Easiest and automated interpretation procedures thanks to
    • Automated target recognition
    • Optimized tomography with automatic propagation velocity estimation
    • Automatic fusion of 200 and 600 MHz data
    • Pipe and cable detection phase concentrated on the automated target recognition module and tomography and not on difficult to read radar maps
    • 3D data representation
    • Fusion of longitudinal and transversal scans in the same tomographic maps
    • Representation of irregular acquisitions useful for areas with "holes" inside (e.g. gasoline stations, industrial plants, etc...).

All the radar data and analysis results are stored in a relational data base in order to have both a historical archive and to be able to rapidly and efficiently search and select data. Data elaboration, including disturbance and noise reduction filters, gain equalization, tomographic elaboration and estimation of propagation parameters (penetration depth, propagation velocity, attenuation, etc.) is fully automatic, thus avoiding mistakes in inserting processing variables and guaranteeing working times.



The GRED 3D UTILITIES module includes all the functions of the previously mentioned modules and in addition contains the automatic target detection management. This procedure is able to detect anomalies with a continuous pattern that can be associated with pipes. Once detected these pipes can be exported in 3D view or directly to CAD/GIS software.

Shielded anntenas are designed to operate to be generally impervious to electromagnetic interferences and can therefore be used in urban environments. Unshielded antennas are usually of low frequencies i.e <=75MHz and are used in open areas as they are suspectible to eloctromagnetic interference and application is therefore limited to geophysical investigation.

Mapping of Underground Utilities
As built maps of utilities are made in reference to specific points, which become null and void as the civic layout changes. Most times, such maps do not even exist. The utilities are often confronted with the task of ensuring expansion of buried services, without knowing the locations or routes of their utility assets. The contractor is bestowed the responsibility to execute the work of new installation of cables or pipes or even over ground structures such as fly over’s, freeways or buildings without damaging existing buried cable and pipe utility services. The task faced by the contractor (or the user i.e the utility itself) is applicable to all types of utilities and especially buried utilities such as water pipes, sewer pipes, power cables etc. The onus of avoidance of buried utilities is of the contractor. Many a contractor recognize that they are faced with the task of mapping ...
When is a ground penetrating radar beneficial in locating of underground pipes & cable utilities ?
The task of Locating underground utilities can be bifurcated into two deliverable: 1.Detection of underground utilities 2.Mapping of underground utilities If we take“a”this can be further subdivided into: 1. Detection of metallic cables & pipes, whether energized current carrying utilities or non energized utilities such as signaling cables, metallic pipes etc. 2. Detection of DI pipes, metallic manholes etc. 3. Non metallic HDPE telecom pipes, fiberglass manholes, etc. Underground cable & pipe utility locating requires the use a combination of various equipment’s and techniques which need to be chosen based on desired deliverables and then correctly employed to obtain the desired results. If the answer is “i”, an operator with basic training on usage of the ever dependable CSCOPE DXL2 Cable avoidance tool or CAT33XD Cable avoidance tool, can do the job blindfolded. If the answer is “ii”, an additional metal detector &/or magnetic locator is required. If the answer is “iii”. The use of a ...
Stop Before You Dig
The civic layout of India based on the growing need for housing and roads has changed beyond recognition.  As a result As-built maps of underground utility assets, if existing , have been rendered redundant and cannot be used for reference for presence of buried utility assets. Jcb Excavators or manual labour at work in the country are digging in the blind at most times, at the peril of significant safety concerns of digging directly into live high voltage cables. Such cuts of buried cables can lead to , in order of priority , fatality to the person excavating and serious losses to the company who has taken the work contract. Not to mention the relative inconvenience to the citizens. The underground space is a jungle of energised power cables, dead power cables, water pipes, jelly filled telephone cables and optical fiber cables. The detection of these assets is ...
