ground radar metal detectors The ground radar or GPR allows detection of very large objects or cavities at depths that no detector even with a frame can reach. Using a different frequency sensor can also focus on smaller targets. These devices, originally reserved for professional use in engineering, are democratized.
Rover UC (UnderCover) Ground Radar Systems All OKM technology that fits in the hand. Ideal for easy transport and remain discreet! The Rover UC metal detector inaugurated a new generation of compact measuring apparatus and cannot be recognized as a metal detector. With the smartphone as a central unit you get the performance.
Ground radars to search for buried treasure deep It is recommended that ground radars to search for buried treasure, and detect underground cavities, such as tombs, tunnels and foundations with secret caches. Ground radar differs from classic metal detector technology and strength. Find metal detector gold to maximum 60 centimeters at ground radars.
Authentic ground radars, also referred to as GPR, allow the detection of metal targets and the cavities at inaccessible depths to other detection systems. But beware, a GPR is used not as easily as a metal detector. Indeed, there are a number of constraints to respect. Field must be completely dry, even in depth, because...Read Post

Job radar subsurface sensing device (a common terminology – GPR) is based on the classical principles of radar. Transmitting antenna device emitted ultra short electromagnetic pulses (units and fraction of a nanosecond) with 1.0-1.5 period of quasi-harmonic signal and a fairly wide range of radiation. The central frequency of the signal is determined by the type of antenna.
Select pulse is determined by sensing the necessary depth and resolution of the instrument. For the formation of probe pulses used broadband excitation of the transmitting antenna voltage drop (shock excitation method).
Emitted in the investigated medium pulse reflected off objects in it or inhomogeneous medium, the medium having excellent dielectric constant or conductivity, received by the receiving antenna, amplified wide band amplifier, converted to digital form by an analog-to-digital converter and stored for further processing. After processing the information received is displayed on the display…Read Post
Profiling provides a vertical sectional view of the subsurface environment along the path of measurement in real time. However, the role of the vertical coordinate performs during the pulse to travel from the transmitter to the boundary of the reflecting object and then to the receiving antenna. To convert this “temporary cut” in the real depth is necessary to estimate the velocity of propagation of electromagnetic waves in the environment and take into account the location of the point of reflection about the antenna device.
Propagation velocity of the probe pulse needed to assess the real depth of the objects can be found directly from the temporary cut in the presence of local or on the track linearly extended across the road subsurface object forming at radarogram characteristic hyperbolic trail. Solution corresponding asymptotes of the hyperbola depends on the speed of wave propagation in the medium. Function determining the speed of propagation of electromagnetic waves in a medium according to the diffraction image of a hyperbolic local object in the device has not been implemented and it is expected to available software systems GPR data processing on a computer…Read Post
