Description
The GPR desertgold gpr send repeating short pulses at high frequency electromagnetic antenna. When the electromagnetic pulse encounters a surface in the subsoil with different permeability or mineralization, a part of the incident energy is reflected and received by the receiving antenna, and a part continues in the Lower floor.
Moving along a predetermined pattern on the surface, one obtains a two-dimensional representation, It can ‘calculate the depth of the reflections and of the objects roughly knowing the propagation speed Vm of the radar waves and to the characteristic physical-electrical conductivity of the ground, so’ after having set these data the depth of any detected objects is estimated or calculated through analysis of the signals or with experimental tests of calibration.
The frequency of the electromagnetic signal emitted varies with the antenna installed on the system and therefore desertgold gpr ‘250 MHz, 150 MHz, 50 MHz, and in the frequency range “radar”
The choice of antenna is made from time to time, depending on the specific issues to be addressed. In general, a lower frequency of the emitted signal (longer wavelength), give best resul for
The signals received by the receiving antenna are directly displayed on the monitor of the instrument (or a laptop), to then be processed and interpreted with the use of software and filters
