RAMAC/X3M™-The Integrated Radar Control Unit
The RAMAC X3M is the smallest GPR system commercially available on the market.
The RAMAC X3M is an integrated radar control unit, fitted directly on the shielded antenna and powered externally. The built-in electronic design makes it low weight and compact size system, easier to assemble and operate. No cable is required since the unit communicates directly with the laptop.
The RAMAC/X3M in brief:
- Operates with the 100, 250, 500 and 800 MHz RAMAC/GPR shielded antennas
- Autostacking function to secure best data quality
- High power autonomy
- Low-weight & compact
- Built-in electronics
- Windows based acquisition software
RAMAC/GPR
The RAMAC/GPR is a truly modular and lightweight GPR system developed by Malå GeoScience.
Its interchangeable features make it available in single-channel or multi-channel systems, compatible with our shielded, unshielded or borehole antennas. So that's a choice of more then ten different single channel configurations ranging from 25 MHz to 1Gz, and up to sixteen simultaneous recording channels in multi-channel mode, all operated from a unique Control Unit.
Single channel RAMAC/GPR
The key part of a RAMAC/GPR is the unique control unit CUII. It connects to any of our standard antennas via an antenna electronics fitted directly onto the antenna itself. Fiber optic cable connection between electronics and ECP communication between CUII and computer ensure a high and safe data transfer. The use of optical fibers enables a separation between antennas of several hundred meters, operating in standard reflection mode, tomography mode or velocity (CMP) mode of operation.
Multi-channel RAMAC/GPR
By adding on a light and compact module to the control unit CUII, the RAMAC GPR becomes a multi-channel system. The Multi-Channel Unit is available in two versions: MC-4 with up to four or MC-16 with up to sixteen recording channels. The unique multiplexing feature between either of the transmitters and receivers of the Multi-Channel Unit is controlled through the Ground Vision™ software.
RAMAC Monitor
The RAMAC XV series monitor is designed with a new user interface, easy to learn and simple to operate even under extremely tough conditions. The unit does any kind of data acquisition with the X3M, X3M Corder or the Control Unit CUII. The monitor is compatible with the whole suite of RAMAC/GPR shielded, unshielded and borehole antennas. Designed on a Linux platform the unit starts up quickly and has very low power consumption. Equipped with a simple control button ”turn and push” and a full size transreflective TFT colour screen the RAMAC Monitor visualizes your data even in strong sunlight and operates under extremely rough weather conditions. The RAMAC Monitor offers a number of advantages over a standard laptop.
- This user interface is a compact, rugged and weather proof monitor
- Will operate within -20° to +50° Celsius
- Has a full size transreflective TFT colour screen with 640 x 480 pixels for best outdoor performance
- No keyboard needed as it is a one-button operation (turn and push)
- System can be operated with gloves
- Display can also be operated with its backlight
Antennas
Shielded Antennas
Shielded antennas are primarily used for mid to high resolution radar surveys.
Common applications include: cable, pipe, UST and void detection; road surveys; quality assurance of concrete constructions; archaeological surveys; ice thickness and frost layer detection; etc.
Shielded antennas, developed and manufactured by MALÅ GeoScience, are made lightweight and as compact as can be to facilitate measurements in small and narrow places. In order to reduce cost for users all the antennas (except the 1000 MHz antenna) have interchangeable antenna electronics and encoder wheels. All antennas are, of course, one-man operable.
Unshielded Antennas
The unshielded low frequency antennas are primarily used for deep penetration radar surveys. Optimized for measurements in field and forest terrain.
Common applications include: detection of soil and bedrock strata; cable, pipe, UST and void detection; archaeological investigations; bathymetry studies; glacial and polar investigations; sedimentological studies; etc.
Borehole Antennas
Used for soil and bedrock investigations in boreholes. The area of investigation is a cylinder shaped volume around the borehole with a radius of 10-100m (dependent on electrical properties of the media).
Common applications include: fracture, cavity and void detection; flow path analysis; localization of "lost" boreholes; delineation of ores; earth dam investigations, foundation engineering, contamination transportation; etc.
The RAMAC/GPR borehole system is the only commercially available borehole radar system in the world that can perform surveys deeper than 30 meters.
Common measurement methods include borehole reflection, borehole tomography and borehole to surface measurements.
RTC Antenna
The concept comprises a one-piece 50 MHz flexible antenna to be connected to the RAMAC/GPR Control unit.
The RTC (Rough Terrain Concept) Antenna is designed to operate by one person in the most extreme environments. This is made possible due to the articulated/flexible design of the RTC.
The electronics are secure inside a metal case, and the flexible antenna elements enable the system to curve and bend along a single-track profile for optimal ground-coupling even in the roughest terrains.
Together with the new XV monitor series it makes GPR easier to use and inherently more efficient in the field. The RTC is a 50 MHz unshielded GPR antenna commonly used for deep/geological investigations. Other applications include: glaciology, archaeological/anthropological investigations, mapping of groundwater and depth to bedrock mapping.
