Ground penetrating radar frequency

GSSI antennas feature the highest signal-to-noise ratio of any antenna available in the industry, providing the highest quality data with clear and accurate . Antenna frequency is one major factor in depth penetration. The higher the frequency of the antenna, the shallower into the ground it will penetrate.

Every GPR system contains one or multiple antennas.

These antennas transmit and receive radio frequency waves.

Upon transmission, these radio waves penetrate the surface that the user intends to investigate if and when the antenna is touching or in close proximity to the surface. While much of the signal dissipates, . Ground penetrating radar : antenna frequencies and maximum probable depths of penetration in Quaternary sediments. Department of Geography, University of Calgary, Calgary, Alta. The technical design of ground penetrating radars can be classified into two groups. GPR systems that transmit an impulse and receive the reflected signal from the target are called Pulsed . The GPR method images structures in the ground that are related to changes in dielectric properties.

The above table shows the maximum penetration that the different antenna frequencies are capable of achieving. In practice the limiting factor is is generally dictated by ground conditions. It does not work well in heavy clay soils where depth penetration is severely compromised.

We have found that this sedimentary field environment (quartzose-rich, thick, inclined gravel strata) is the most . The SFGPR system has been developed to improve the maximum penetration depth capability of ground penetrating radar ( GPR ) applications without degradation of . Your choice of Ground Penetrating Radar system depends largely on how deep you need to see. The lower the frequency of the antennae, the deeper you can see. Our radar systems offer both single and multi- frequency systems. Different length antennae send different frequency . On the other han penetration of radio waves into the ground decays rapidly with increasing frequency , so the center frequency needs to be as low as possible.
