Ground Penetrating Radar Model Simulation for Detection of Coastal Embankment
نویسندگان
چکیده
In recent years, the ground penetrating radar (GPR) is increasingly used in the detection of riprap embankments. In order to analyze the costal embankment with explosive compaction, model experiments are conducted to investigate the influence of seawater on the signal and image of GPR, especially to figure out the image variation of riprap bottom boundary. The influence of immersion of seawater to dielectric permittivity is discussed through laboratory test. The results suggest that the average dielectric permittivity for the mixture of crushedstone and seawater can be measured effectively by GPR. Moreover, inclusion of seawater will result in the increasing of riprap permittivity and can attenuate the signal of reflection wave from riprap bottom boundary.

The Use of Ground Penetrating Radar for the Detection and Study of a Buried Marble and in Situ Location of Possible Cracks
This work described the use of two methods to detect possible abnormalities, debris and cracks inside block of marble. The first method was based on the direct detection of block of marble buried at depth of 0.2 m using Ground Penetrating Radar (GPR). The second method was based on the use of simulation software named GprMax2D for the same block but at depth of 0.5 m. Our results showed that GP...

Ground penetrating radar (GPR) has gained a distinguished place during recent years as a tool for investigating subsurface objects, yet its output is of low resolution, and in need of further processing in order to make its output readily interpretable. Furthermore, GPR data collected in a typical survey is usually in large quantities, and dealing with such quantities manually to produce final ...
متن کاملProgress in the Research of Ground Bounce Removal for Landmine Detection with Ground Penetrating Radar
Downward looking ground penetrating radar (GPR) has been considered a viable technology for landmine detection. For such a GPR with the antennas positioned very close to the ground surface, the reflections from the ground surface, i.e., the ground bounce, are very strong and can completely dominate the weak returns from shallowly buried plastic mines. Hence, one of the key challenges of using G...

Ground penetrating Radar (GPR) is an interesting device that can allow a non-destructive auscultation of the underground without any excavation. It is based on the use of high frequency electromagnetic waves, including reflection or diffraction that allows the detection of buried objects. In this work, we studied the possibility of using GPR for detecting of human targets under the rubble cause...
