GPR (Ground Penetrating Radar) is one of subsurface sensing technologies, which has been used intensively since 1980s. Due to rapid development of both hardware and software, its possibilities have been considerably extended resulting in widening the area of its applications. While such applications as to detection of buried pipes and cables, archaeology and geology are established category, ne...

ground penetrating radar (gpr) and magnetic methods were used at ghasr-e-shirin town in kermanshah province, southwest of iran for detecting a series of large ancient (ca 1500 years) underground cavities (tagh). the area of study is a historical monument which is named as emarat e khosro. radar and total intensity magnetic field measurements have been done on the eastern part of the complex, wh...

The Spaceborne Imaging Radar-c/X-band Synthetic Aperture Radar (SIR-C/X-SAR) mission was a cooperative endeavor of the United States, Germany, and Italy. The SIR-C/X-SAR scientific research program was a large international cooperative program of radar for Earth observation in which 13 countries participated, including China. SIR-C/X-SAR, with the ability to acquire polarimetric SAR and integer...

To optimize the effectiveness of the rehabilitation of underground utilities, taking in consideration limitation of available resources, there is a need for a cost effective and efficient sensing systems capable of providing effective, in real time and in situ, measurement of infrastructural characteristics. To carry out accurate non-destructive condition assessment of buried and above ground i...

Surface crevasses covered by snow bridges can be mapped remotely on ice sheets and glaciers using active microwave synthetic aperture radar. They are highlighted against the surrounding due to increased scattering from side-walls base of usually appear as linear features. The contrast between crevasse-free regions depends design sensor, image acquisition parameters properties snow. Here we quan...

Ground-penetrating radar (GPR) has recently gained a wide acceptance in the archaeological community as a method that can quickly and accurately locate buried archaeological features, artifacts, and important cultural strata in the near-surface. The GPR method has been especially effective in certain sediments and soils between about 20 cm and 5 m below the ground surface, where the targets to ...

This paper presents an approach that how to locate and to detect obstacle or hurdles or the human being or any living being, using synthetic aperture radar (SAR). The paper consist of the acknowledgement of idea how to trace the any moving object on earth level or above the earth level bye using GMTI(Ground Moving Target Indicator) or synthetic aperture radar SAR. It is demonstrated that SAR pr...

ground penetrating radar (gpr) method as a high resolution non-destructive geophysical method is used for detection of shallow subsurface targets. this method is based on the transmission of electromagnetic waves inside the earth and recording the reflected waves from the subsurface. as the method uses high-frequency electromagnetic waves in the frequency ranges of 12.5 to 2500 mhz (called gpr ...
