Ground-penetrating radar (GPR) is a geophysical and close-range remote sensing technique based on the use of radar pulses to obtain cross-section images of underground features. This method is characterized by the transmission of an electromagnetic short length pulse (1-2 ns), presenting a centre frequency ranging from 10 MHz to 2.5 GHz. The principles of GPR operation are based on the ability ...

This paper presents a new ground penetrating radar (GPR) design approach using orthogonal frequency division multiplexing (OFDM) and compressive sensing (CS) algorithms. OFDM technique is applied to leverage GPR operating speed with multiple frequency tones transmission and receiving concurrently, and CS technique allows utilizing reduced frequency tones without compromising data reconstruction...

Ground Penetrating Radar (GPR) is an imaging technique that uses wide-band nonsinusoidal electromagnetic waves to produce high-resolution images of the subsurface typically from 0-–10 m depth. GPR is an effective tool for subsurface inspection and quality control on engineering construction projects. The survey method is rapid, nondestructive and noninvasive. GPR has been successfully applied t...

The European Global Product Realization (E-GPR) project represents the main practical part of the E-GPR course organized by 3 European universities: the Swiss Federal Institute of Technology of Lausanne, the Technical University of Delft and the University of Ljubljana. It is defined in collaboration with the industrial partner(s) of the E-GPR course and consists of developing a global product ...

methods, intensive efforts have been undertaken to supplement the scarcity of hydrogeological data with densely We combine electromagnetic inversion of ground penetrating radar sampled geophysical data (Beres and Haeni, 1991; Ru(GPR) signals with hydrodynamic inverse modeling to identify the effective soil hydraulic properties of a sand in laboratory conditions. bin et al., 1992; Hubbard et al....

Connecticut established telephone-based gram-positive rod (GPR) reporting primarily to detect inhalational anthrax cases more quickly. From March to December 2003, annualized incidence of blood isolates was 21.3/100,000 persons; reports included 293 Corynebacterium spp., 193 Bacillus spp., 73 Clostridium spp., 26 Lactobacillus spp., and 49 other genera. Around-the-clock GPR reporting has descri...

Soil Moisture (SM) is one of the most critical factors for a crop’s growth, yield, and quality. Although Ground-Penetrating RADAR (GPR) commonly used in satelite observation to analyze soil moisture, it not cost-effective agricultural applications. Automotive uses concept Frequency-Modulated Continuous Wave (FMCW) more competitive terms price. This paper evaluates viability using as substitute ...
