t. e. Treblinka (pronounced [trɛˈbliŋka]) was the second-deadliest extermination camp to be built and operated by Nazi Germany in occupied Poland during World War II. [2] It was in a forest north-east of Warsaw, 4 km (2.5 mi) south of the village of Treblinka in what is now the Masovian Voivodeship.
Ground-penetrating radar (GPR) is a geophysical method that uses radar pulses to image the subsurface. It is a non-intrusive method of surveying the sub-surface to investigate underground utilities such as concrete, asphalt, metals, pipes, cables or masonry. [1] This nondestructive method uses electromagnetic radiation in the microwave band ...
John Call Cook (April 7, 1918 – October 12, 2012) was an American geophysicist who played a crucial role in establishing the field of ground-penetrating radar and is generally regarded as contributing the fundamental research to develop the field. [2] Cook is also known for demonstrating that aerial surveys can map surface radioactivity to ...
RailSAR. The railSAR, also known as the ultra-wideband Foliage Penetration Synthetic Aperture Radar (UWB FOPEN SAR), is a rail-guided, low-frequency impulse radar system that can detect and discern target objects hidden behind foliage. [1] [2] It was designed and developed by the U.S. Army Research Laboratory (ARL) in the early 1990s in order ...
Automatic ground penetrating Radar (upGPR) near Swiss Camp ( Greenland) Near-surface geophysics is the use of geophysical methods to investigate small-scale features in the shallow (tens of meters) subsurface. [ 1] It is closely related to applied geophysics or exploration geophysics. Methods used include seismic refraction and reflection ...
Alexander Peter Annan is an engineer whose research focuses on near-surface geophysics. He has made significant contributions to the development of ground-penetrating radar (GPR) technology. [ 1] Annan is the CEO of Sensors & Software, a company he founded to commercialize GPR technology. He has been working on the development of GPR since the ...
The frequency range for this type of ground penetrating radar equipment is 10-2300 MHz with a peak frequency between 100 and 1000 MHz and pulse duration of 0.2 to 4.0 ns. More than 50,000 lineal feet of data can be collected and stored in the US Radar unit before being transferred via USB port to a Windows-based operating system that processes ...
Introduction date. 1980. Map all coordinates using OpenStreetMap. The Tethered Aerostat Radar System (TARS) [2] is an American low-level airborne ground surveillance system that uses aerostats (moored balloons) as radar platforms. Similar systems include the EL/M-2083 and JLENS.
