Raptor-45

450 MHz frequency

Raptor-45 has a center frequency of 450 MHz. Arrays configured with Raptor 45-units are suitable for utility mapping, archaeological investigations and railway investigations, among other applications.

Raptor-80

800 MHz frequency

Raptor-80 has a center frequency of 800 MHz and is hence suitable for applications where higher resolutions are needed, roadbed layers, concrete scanning etc.

Raptor Pushcart Carrier – Easy to Set Up and Adjust!

A mounting bracket on the front of the Raptor pushcart allows for quick fitting/removal of the guidance wheel. The guidance wheel is available in either 150 mm or 300 mm diameter, so you can choose the small or large option to suit your survey conditions. Each wheel type incorporates a quick-release mechanism so it can be swapped out in a matter of seconds. The mounting bracket also offers a convenient mounting point for user-designed accessories for bespoke arrangements.

We are pleased to announce a redesign to the internal mechanics of the Raptor vehicle-mount carrier. This change increases the flexibility of the Raptor 3D GPR array solution by enabling quicker reconfiguration between the Raptor pushcart and vehicle-mount carriers. While it has always been possible to make such changes due to Raptor’s modular design, the accompanying video shows how this new arrangement makes it that much easier and faster.

Benefits

• Quickly change configurations to suit site conditions
• Serve a broader range of projects
• Save money on equipment investment

Condor is modern processing, visualisation and interpretation software for the efficient management of Raptor 3D GPR array data.

Talon-2 data acquisition and control software

The modular design plug and play configuration make it easy to design any numbers of channels from a minimum of 4, up to a maximum of 30, or bespoke user-defined solutions. This allows you to tailor your own array arrangement and carrier solution to meet your specific needs.

ViewR – Windows Visualization Software

ImpuseRadar ViewR is a new Windows-based software utility that lets users 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) .

GPR Array-3D data gathering and processing

The requirement to survey over larger areas and apply 3D processing and visualization processes has led to the development of advanced GPR systems that comprise multiple GPR antennas connected to form a GPR array. The ImpulseRadar Raptor solution contains several individual antenna elements (transmitters and receivers), which are arranged to form multiple measurement channels that operate simultaneously and are closely spaced to each other.

There are several benefits with 3D-GPR surveys vs single line data collection – no loss of information, true-3D visualizations and almost photography-like images, easier to interpret due to their intuitive character:

• The traditional approach with multiple parallel lines, sometimes in a perpendicular grid pattern, where often gathered with line spacing in the order of half a meter. Since a GPR may have a spatial resolution in the order of a few centimetres, this leads to aliasing, or in other words loss of information. When using a Raptor array, the individual line spacing will be 8 or 4 [cm]. Imagine collecting data with 4 [cm] line spacing over a few hectares, with a single channel antenna, almost undoable. In short, Raptor data is of significantly higher reliability compared to any 2D dataset.
• The dense datasets gathered with Raptor enables a user to view data from any direction, without the interpolation artefacts seen commonly in approaches to 3D data gathering with single-channel antennas.
• Although the Raptor system may seem more complicated compared to an ordinary GPR-system, the following interpretation is significantly easier. The 3D-processes yields photography-like images which greatly simplify the otherwise tedious work of interpretation. It becomes a very intuitive process.
