New ground penetrating radar probes sand and rocks


The exhibition "Archimedes-2013" inventors showed a compact device that allows you to peek into the ground for two dozen meters.

Interest to the riches of the underworld has always been a man. Suffice it to recall the treasures of ancient civilizations, historical or legendary pirate treasure.

With the development of technology zone of interests and areas of underground sensing expanded significantly. Geology, industrial, civil and traffic engineering, archeology, environmental monitoring, forensics, conducting anti-terrorist operations. Today, efficient and easy to work georadar equipment for underground sensing is widely in demand.  

The principle of operation of industrial GPR is based on the emission and reception of the reflected signals from the broadband interfaces between layers sensed medium items or irregularities that are different from the medium dielectric constant or conductivity. The reflected signal is processed and displayed directly on the screen, quickly giving a picture of the "underworld".

Original innovation in this field has shown at the exhibition "Archimedes-2013" Moscow engineers. The new lightweight and compact ground penetrating radar (folded it fits into the size of a briefcase.) With its high sensitivity, it can carry out sensing in a variety of soils, working with up to 3.5 hours of battery life. Maximum depth sensing device to 20m, depending on the soil type and condition.

The area of industrial applications is very broad trends. In the first place — is sounding underground utilities, various metallic and non-metallic objects (cables, pipes, foundations, masonry and other). In addition, the GPR can be geological sections of the upper layers of soil, identify the boundaries of water lens floating earth, ice, water table position.
Another application — sensing the state of soils (cavities and wetlands) under paving, sounding caverns, large boulders. Finally, the search for end-of-century technology, unexploded ordnance.

New product allows for sensing in a variety of environments — in dry, sandy soil, rock formations, frozen and wet sandy soils, the limestone.
