Visualised: Groundradar’s 12 months of travel
The map shows all travel conducted to and from GPR projects worldwide by Groundradar staff over the past 12 months (August 2010 – August 2011). In total, nearly 400,000 miles were flown during the period, landing in 39 countries.
Radar through the world’s tallest dunes
Groundradar has just returned from an R&D project in Namibia, where UltraGPR was used to profile various dune forms as part of an on-going research project using radar to construct petroleum reservoir analogies. Dune 45, a star dune near Sussusvlei, is known as the “world’s most photographed dune” and has been a default wallpaper on Microsoft Windows (98, XP, Vista, 7). The radar profile shows the base of the dune to 70 m. The profile was acquired along a ridge of dune, resulting in unremarkable internal structures. The Sussusvlei dunes are believed to be amongst the tallest in the world.
MineVue project nears completion
A two-year development and testing project is drawing to a close with the imminent delivery of the first MineVue long-range radar system to the Government of India. MineVue is the longest-range shielded radar system commercially available. It is also the first low-frequency Intrinsically Safe (ATEX) radar system in the world, suitable for use in underground coal mines.
Groundradar commences research on new radar design
Working with an international team of radar electronics specialists, Groundradar has initiated a project to develop the next-generation radar architecture for long-range imaging applications. The project involves the use of novel shielded antenna concepts with a continuous wave (CW) radar to achieve maximum penetration. The targeted applications would be deep mining exploration projects where radar image textural variations are of interest (e.g. BIFs) and seismic static corrections.
Groundradar has conducted surveys in over 65 countries
With the recent addition of Suriname, Groundradar has now conducted GPR surveys in every South American nation, from Colombia to Chile. Suriname also brings the total countries Groundradar has worked in to over 65.
Groundradar fully booked through May, 2011
Groundradar’s survey teams have been committed to a series of projects which will extend until May, 2011. New projects are being undertaken in Algeria, Angola, Brazil, the Congo, Cuba, India, Indonesia, Jamaica, Libya, Madagascar, Sierra Leone, South Africa and Suriname between January – May, 2011. The volume of GPR surveying during the first half of 2011 period is expected to exceed all of 2010.
Groundradar conducts surveys in 23 countries in 2010
Groundradar celebrated its busiest year in 2010, with GPR projects completed in 23 countries on all six continents. Environments ranged from the jungles of the Congo to the Outback of Australia, in temperatures ranging from +40 C (Algeria) to -35 C (Far East Russia). As industry acceptance of long-range radar grows, Groundradar’s schedule appears even busier in 2011, with all survey teams already booked through late April.
Visit Groundradar at PDAC Booth 702
Groundradar will be exhibiting at the PDAC in Toronto, Canada (March 6-9), the world’s largest annual mining convention Visit booth 702 to learn more about Groundradar’s unique long-range GPR technology for mineral resource evaluations.
Groundradar receives custom dielectric probe in Estonia
Groundradar has recently visited Estonia to take delivery of a custom dielectric permittivity probe, which is also capable of providing electrical conductivity and soil moisture readings. As the potential applications for Groundradar’s proprietary long-range GPR instruments grow, traditional limitations on suitable GPR survey locations are increasingly challenged. Groundradar will use the new probes at a variety of new application sites worldwide to test parameters critical to the prediction of radar performance. Clients may now employ this instrument prior to Groundradar’s mobilisation to provide critical measurements which Groundradar will use to determine the maximum predicted range and resolution of a survey, as well as the most suitable radar system for the task.
MineVue deployed in August to India, Australia, Papua New Guinea and Indonesia
Groundradar’s latest custom long-range radar system, MineVue, has been trialled extensively both above and underground at a series of Indian coal mines in Jharkand and West Bengal states. The system was able to detect abandoned coal workings at impressive depths in environments where complete radar shielding was required. 
MineVue was also tested in Papua New Guinea and Australia, where the system was used to detect voids in limestone to depths of over 40 m in cluttered surroundings where traditional low-frequency unshielded radar systems would have been unsuitable. Although limestone is generally an excellent radar environment, some limestones, particularly those with a weathered mantle of clays, can prove problematic for traditional radar equipment. MineVue is a hybrid radar system comprising of a real-time sampling impulse radar as well as a pulse-compression radar which is completely shielded, easily portable, deep penetrating, and continuously tracked by DGPS. 
A challenging laterite project in Indonesia where unshielded antennas have been unsuccessful was the site of further MineVue surveying. The results of trials were very encouraging, opening new applications for custom GPR instrumentation.
