Geophysics / GPR Array-3D Data Collection and Processing
The need to survey larger areas and apply 3D processing and visualization techniques has led to the development of advanced GPR systems that include multiple GPR antennas connected to form a GPR array.
The ImpulseRadar Raptor solution contains several individual antenna elements (transmitters and receivers) that are arranged to form multiple measurement channels operating simultaneously and in close proximity to each other.
Although the Raptor system may seem more complex than a standard GPR system, the following interpretation is significantly simpler. 3D processes produce photo-like images, greatly simplifying otherwise tedious interpretation work. It becomes a very intuitive process.
A GPR array collects far more data in one pass compared to a typical GPR system. But since the Raptor system is also based on real-time technology, surveys along each line are equally fast. As a result, surveying large areas can be done more quickly and efficiently. Routine applications now include utility mapping, archaeological surveys and artifact mapping, road surveys, bridge deck investigations, and more.
Raptor – High-speed 3D Radar Array
Raptor is a cutting-edge high-speed 3D-GPR array that enables very fast collection of 3D GPR data, at speeds exceeding 130 km/h, with intervals of 5 cm.
Raptor is the most advanced GPR-Array solution on the market.
– Enhances performance and improves workflows
– Efficient subsurface mapping: Designed with simplicity in mind, Raptor will help you achieve maximum productivity and optimal results.
– Flexibility: It consists of separable transmitters and receivers that a user can configure for an arbitrary number of channels and for different applications.
Available Antennas
Raptor-45
– Frequency: Raptor-45 has a central frequency of 450 MHz.
– Applications: Arrays configured with Raptor 45 units are suitable for utility mapping, archaeological surveys, and railway investigations, among other applications.
Raptor-80
– Frequency: Raptor-80 has a central frequency of 800 MHz
– Applications: Suitable for applications requiring higher resolutions, roadbed layers, concrete scanning, etc.
Raptor GPR System Options and Flexibility
The system is modular and expandable. Operators can choose the number of receivers/transmitters they need for their application and can build their own antennas using the necessary number of Tx/Rx modules for the survey.
Two configurations are available:
– A pushcart that fits an 8-channel GPR array
– A vehicle mount that accommodates 18 channels (Raptor-45 antennas).
Pushcart – Up to 8 channels (Raptor-45 antennas)
Designed to be manually pushed, it allows up to 8 channels to be arranged with a total width of 0.9 m. The handlebar is fully foldable to reduce the physical footprint, making transport and storage much more efficient. The entire unit can be easily transported in the trunk of a standard family car/station wagon. The new high-capacity rechargeable battery provides up to ten hours of continuous operation.
Easy Installation Kit
This solution increases the flexibility of the Raptor 3D GPR array system by allowing quicker reconfiguration between the Raptor pushcart and vehicle mounts.
– Quickly modify configurations to suit site conditions and survey requirements
– Adapt to a wider range of projects
– Reduce survey times thanks to increased productivity
Software
Condor 3D GPR Processing and Interpretation Software
Condor is a modern processing, visualization, and interpretation software for efficient management of Raptor 3D GPR array data.
The data manager enables practical and intuitive organization of information. The user has full control over views and outputs during various processing stages, while the layer manager offers the same for interpretation procedures.
Talon-2 Data Acquisition and Control Software
The modular plug-and-play design simplifies the configuration of any number of channels from a minimum of 4 to a maximum of 30 or user-defined custom solutions. This allows the customization of the array arrangement and vehicle solution to meet your specific needs. Talon acquisition and control software provides an easy yet effective way to manage data collection quality and external positioning data.
ViewR: Windows-based Viewing Software
ImpuseRadar ViewR is a new Windows-based utility software that allows users to quickly and easily open and view Raptor data files in an interpolated top-view format without importing them into Condor (3D GPR Processing & Interpretation Software).
The ability to review a Raptor project in this way allows you to verify the quality and integrity of your project’s data while still on site. This approach enables you to identify potential issues with critical positioning data quality before leaving the project site, possibly saving expensive return visits or rework.
