Specialists of Timer CJSC and Federal State Unitary Enterprise "All-Russian Electrotechnical Institute named after V.I.Lenin" have held a unique joint experiment to test a modern ground penetrating radar. The usage of a high-power transmitter with a voltage of 50 kV produced by FSUE “AREI” and a GROT 12 receiver manufactured by Timer CJSC has made it possible to carry out Moscow region clay scanning to a depth of 450 meters and for the first time to get a radargram, describing such depths.
The carried out experiment with the use of a GROT 12 type ground penetrating radar has proven the ability to scan the deserts of Africa and permafrost soils of Siberia to depths of several kilometres. Such technology allows avoiding the drilling at places, where there are no objects of interest, and that significantly reduces the costs of preliminary studies and the damage to the environmental.
The created by Timer CJSC receiver allows carrying out soils scanning with the time delays of 64000 ns. The probing depth, while scanning the soils with the pulse propagation speeds of 0.15 m/ns, exceeds 3 km.
