Histori
US Radar Inc. is a manufacturer and innovator of earth penetration radar technology and equipment. The company was formed in 1994 as a sales and marketing partner for America for ERA Technology of Leatherhead, Surrey, UK.
The parent company has developed various subsurface detection systems since its inception in 1920, and developed one of the first modern ground penetration radar systems in the early 1980s. The original aim of this technology was to find plastic landmines as part of the British Ministry of Defense contract. The commercial version of this technology was developed in 1990 after making adjustments to work in the private sector.
In 2002, ERA Technology's Ground Penetrating Radar (GPR) division was acquired by US Radar including manufacturing and engineering capabilities, marketing, support and customer service worldwide. All facilities and many personnel were then transferred to the US.

Technology
Ground penetrating radar is similar in concept with metal detector. This technology works by slowly moving the unit over a non-conductive surface. The antenna sends the ultra-wide RF energy spectrum through the surface which is then reflected back to the antenna to create an image and display it on the unit display. The ultra-wide spectrum RF energy is safe for both the unit operator and the area under investigation. The GPR depth range is limited by the electrical conductivity of the ground, the range of transmitted frequencies and the radiated power.
Hardware
The type of hardware used will vary based on the type of work involved. For example, a unit for finding utilities and for geophysical applications needs to map from anywhere from 15 feet to 100 feet. The frequency range for this type of earth penetrating radar equipment is 10-2300 MHz with peak frequency between 100 and 1000 MHz and a pulse duration of 0.2 to 4.0 ns. More than 50,000 feet of data line can be collected and stored in US Radar Find units before being transferred via USB port to a Windows-based operating system that processes and filters information. The field unit also filters and processes in realtime.
3D mapping can be completed when multiple individual passes are combined and interpolated. All systems and antennas manufactured by US Radar are able to present their data in 3D format with the appropriate software package. When using a unit-equipped 3D software, the software can produce in-depth slice layers, point clouds, and isosurface models.
