1. 1. Non-Destructive testing of concrete with ground penetrating radar

   University essay from Luleå tekniska universitet/Byggkonstruktion och brand

   Author : Elias Hammarström; [2018]
   Keywords : Concrete; Non-destructive testing; Ground Penetrating Radar GPR ; Assessment; Inspection;

   Abstract : Concrete structures are susceptible to deterioration over time and it is vital to continually assess concrete structures to maintain the structural integrity and prolong the service life. In recent years there has been an increased interest in non-destructive testing of concrete, i.e. READ MORE

3. 2. Using ground-penetrating Radar to Estimate Sediment Load in and Around TwoBoatLake, Western Greenland

   University essay from Institutionen för geovetenskaper

   Author : Johannes Petrone; [2013]
   Keywords : Greenland; ground-penetrating radar; GPR; sediment; load; thickness; MATLAB;

   Abstract : In a periglacial environment it is important to know the thickness, orientation and structureof sediments when assessing the landscape and its hydrological pathways. Using a groundpenetratingradar (GPR) I have profiled large areas of the subsurface in a catchment area to alake on western Greenland. READ MORE

4. 3. Evaluation of weighting functions for Sidelobe control in UWB SAR image processing

   University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

   Author : Habiba Akhter; [2013]
   Keywords : Image processing; Synthetic aperture radar SAR ; Ultra Wideband UWB ; Apodization; Impulse Response IPR Function;

   Abstract : Ultra wideband (UWB) Synthetic Aperture Radar (SAR) holds huge possibilities for both terrestrial and celestial object sensing with excellent details which assists in science and technology. SAR systems associated with large antenna beamwidth, large signal bandwidth and low frequency operating in the VHF/UHF region is becoming gradually more popular because of their rising number of application in the areas of ground-penetrating radar (GPR) and foliage penetration radar (FOPEN).

5. 4. Oil Well Monitoring by Ultra-wideband Ground Penetrating Synthetic Aperture Radar

   University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

   Author : Daniel Oloumi; [2012]
   Keywords : Ground penetrating radar; Synthetic aperture radar; Ultra-wide-band radar; Ultra-wide-band horn antenna ;

   Abstract : Radar has been used for remote sensing and surveillance for decades. Nowadays radar remote sensing and radar surveillance is used for many different things in the modern society. Radar can sense objects or environments from very long distance. Electromagnetic radar waves can work where and when light cannot. READ MORE

6. 5. Signal Processing Using Wavelets in a Ground Penetrating Radar System

   University essay from Institutionen för systemteknik

   Author : Thomas Andréasson; [2003]
   Keywords : Technology; wavelet; wavelet packet; feature extraction; mine detection; TEKNIKVETENSKAP;

   Abstract : This master's thesis explores whether time-frequency techniques can be utilized in a ground penetrating radar system. The system studied is the HUMUS system which has been developed at FOI, and which is used for the detection and classification of buried land mines. The objective of this master's thesis is twofold.
