MALÅ 3D Imaging Radar Array (MIRA)
The MALÅ MIRA HDR multi-channel GPR is built on the latest HDR technology, which able to collect best possible data quality, resolution and better depth penetration in comparison to the conventional GPR.
Using improved mechanical design and modern software, the MALA MIRA HDR GPR system is able to produces data with less noise, higher speeds and with more functionality.
As such the MIRA HDR is highly recommended for large area mapping as it will be cost-effective and time saving.
HDR Technology Explained
The MALÅ HDR technology produces data with significantly lower noise levels, compared to traditional GPR systems. As illustrated in the graph below, a lower noise floor gives a wider bandwidth when compared to conventional time-interleaved systems.
This means clearer data with less background interference, able to generate sharper data with higher contrast, enable user to see deeper than non-HDR systems.
MIRA CUSTOM ANTENNA ARRAY
The MALÅ MIRA HDR GPR have the highest point density on the market, thus able to delivers unsurpassed class-leading resolution.
It is certified according to EC/FCC/IC and is housed in a rugged IP65 casing. It utilizes unique HDR technology, allowing for the collection of precise, high-resolution data with the capability to record down to a depth of 5 m in good condition.
The flexible solution, providing 132 possible data channels and a channel spacing of 6.5 cm, delivers 32-bit data with the highest resolution on the market, even at highway speed.
The system enables any combination between the individual receiver and transmitter antennas used in the array; an important tool when measuring e.g. moisture content of roadbeds, railway embankments and runway constructions.
MIRA HDR uses an integrated internal GPS receiver for exact time-stamping of each individual data point (trace). Any external device utilizing PPS time can be synchronized with the GPR data, e.g. positioning devices, video recordings or other types of supportive data.
MIRAsoft HDR Data Acquisition Software
MIRAsoft HDR is easy to use data acquisition software designed for the MIRA HDR system.
- It enables you to monitor the performance and data collection in detail.
- It assists in keeping the correct speed and course, showing you real-time slice views and swath coverage on top of moving maps, available both on- and offline.

Application
The MIRA HDR is designed to produce superb data quality at high speeds. The wide coverage and the highest channel density on the market means fewer passes and higher resolution. The MIRA HDR can collect quality data at highway speeds. At lower speeds the excess data is stacked, producing clearer data while still having the ability to cover tens of hectares per day.
ROAD SURVEYS
To analyse roads, bridgedecks and railways, you have to be able to keep up. That is why the MIRA HDR is built to operate at highway speeds. The channel configuration assists in covering a wide swath, meaning you need fewer passes to complete a survey.
UTILITY DETECTION
The MIRA HDR is the perfect solution for large area mapping of underground metallic and/or non-metallic utilities such as pipes, cables, conduits and ducts. Create detailed 3D maps of the subsurface with the highest resolution on the market and avoid causing damage to installations while excavating.
ARCHAEOLOGICAL PROSPECTING
Because of its high resolution, the MIRA HDR can produce very detailed images of small archaeological features, such as pits, postholes and hearths. It has the ability to cover tens of hectares of land per day in a non-destructive way, which makes it a very cost effective tool.
CAVITY DETECTION
Map the underlying geology to identify dangerous features such as sinkholes. The MIRA HDR antenna technology detects both larger and smaller cavities, allowing you to contain and address cavities before they collapse.
