Penetration with Step Frequency Ground Penetrating Radar
نویسنده
چکیده
where P is the transmitted power, τ is the integration time, Gt and Gr are the transmit and receive antenna gains, λ1 and λ2 are the longest and shortest wave lengths respectively, σ is the target radar cross section, R is the target range, k is Boltzmanns constant, T is the effective receiver noise temperature and B is the receiver bandwidth. In the case of GPR, the signal attenuation in the ground has exponential character, hence the exponential loss factor. For the development of this equation, please see “Development of the ultra wide band step frequency radar equation“ at the end of this paper.

متن کاملSubsurface imaging with low frequency SAR Field validation in Egypt using a Ground-Penetrating Radar
We study the capabilities of low frequency radar systems to sound the subsurface in arid countries. This approach is based on the coupling between two complementary radar techniques: the airborne Synthetic Aperture Radar (SAR) used in L-band (1.2 GHz) for imaging large scale subsurface structures, and the Ground-Penetrating Radar (GPR) used between 500 and 900 MHz for sounding soils at a local ...

Autonomous UGVs (unmanned ground vehicles) has been extensively investigated it’s capabilities for military applications. In order to operate the UGVs on the open fields, they must be able to detect obstacles (eg. holes, stumps, rocks, etc) concealed behind vegetation canopies, as well as to detect surface. Forward looking imaging radar is necessary to autonomous UGVs for collision avoidance an...
متن کاملProcessing a multifold ground penetration radar data using common-diffraction-surface stack method
Recently, the non-destructive methods have become of interest to the scientists in various fields. One of these method is Ground Penetration Radar (GPR), which can provide a valuable information from underground structures in a friendly environment and cost-effective way. To increase the signal-to-noise (S/N) ratio of the GPR data, multi-fold acquisition is performed, and the Common-Mid-Points ...
