Eddy current sensors held by us, got the necessary certificate, which allows them to work in clearing area of dangerous materials and explosives.
FULKO Krzysztof Staniec Company works with detectors of domestic and foreign production. By using these detectors it is possible to clean the terrain up to 15 meters depth.
GPR Mala GeoScience ProEx
The GPR method belongs to the genus of electromagnetic measurements, which allow simultaneous tracking of magnetic and electric properties of the research area. Radar enables the penetration of ground based on counting the delay of electromagnetic pulses of high frequency transmitted by the transmitting antenna, which are reflected from the various ground points (lithological boundaries) and then are received by the receiving antenna and transmitted to the central processing unit in order to count the time of wave latency. The pulses sent by the transmitter antenna, come back from the depths of research point with a delay to the receiving antenna and go to the control system central unit, where they are where they are processed and sent to the recorder. The effect of electromagnetic wave reflection from the boundary of two different environments is caused by the difference between the dielectric values on both sides. The amplitude of the reflected electromagnetic pulse is proportional to the size of the reflection coefficient at the boundary of two different environments. The higher, the greater contrast of the dielectric constant on both sides of the border reflective.
GPR Mala Geoscience ProEx System (Professional Explorer). It is a four-channel radar, with improved measurement parameters. In GPR ProEx pulse repetition rate is 200 kHz which allows increasing the speed measurement or the use of higher signal assemblies. Screen antenna is also used in the set with frequency of 500 MHz, which is the best use for archaeological research.
Example of 500 MHz antenna use in archaeological research:
