1. 11. 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

3. 12. Radar and Optical Data Fusion for Object Based Urban Land Cover Mapping

   University essay from KTH/Geodesi och geoinformatik

   Author : Alexander Jacob; [2011]
   Keywords : Data Fusion; Image Segmentation; Object based Mapping; Urban Land Cover; SAR; Radar; Multispectral; Region growing and merging;

   Abstract : The creation and classification of segments for object based urban land cover mapping is the key goal of this master thesis. An algorithm based on region growing and merging was developed, implemented and tested. The synergy effects of a fused data set of SAR and optical imagery were evaluated based on the classification results. READ MORE

4. 13. Focusing Moving Targets Using Range Migration Algorithm in Ultra Wideband Low Frequency Synthetic Aperture Radar

   University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

   Author : Samiur Rahman; [2010]
   Keywords : SAR; UWB; RMA; Stolt interpolation; frequency domain; pulse compression; moving target; focusing; NRS; Doppler shift.;

   Abstract : Ultra wideband (UWB) synthetic aperture radar (SAR) is being used to operate in low frequency for detecting obscured targets beneath the foliage and in the ground from airplanes or satellites. Although it has the obvious military interest, it also possesses civilian applications such as geophysical studies, weather forecasting and so on. READ MORE

5. 14. RFI Suppression in Low Frequency UWB SAR Using the RLS Algorithm

   University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

   Author : Khan Fazal Ullah; [2010]
   Keywords : Aperture; Adaptive Line Enhancement ALE ; Chirp signal; Global BackProjection GBP ; Pulse compression; Radio Frequency Interference RFI ; Synthetic Aperture Radar SAR ; UltraWide Band UWB ;

   Abstract : Synthetic Aperture Radar (SAR) has many applications within ground image sensing and navigation. UltraWide Band(UWB) SAR operating at Ultra High Frequency /Very High Frequency(UHF/VHF) are usually a ffected by the Radio Frequency Interferences(RFI) from civilian communication bands which causes SIR(Signal to Interference Ratio) to go down.

6. 15. Synthetic Aperture Radar Image Quality Measurements

   University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

   Author : Subrata Kumar Das; [2010]
   Keywords : Key Words: SAR; UWB SAR; spatial resolution; differential resolution; ISLR; PSLR; sinc function; IRF-SAR.;

   Abstract : Abstract Synthetic Aperture Radar (SAR) is an important tool for remote sensing now a day. SAR image quality measurements play an important role in the development of SAR image digital processing methods. The essential SAR image quality assessments are spatial resolutions, Integrated Sidelobe Ratio (ISLR) and Peak Sidelobe Ratio (PSLR). READ MORE
