  1. 6. 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).

    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

  4. 9. Development of a GB-SAR System and Perform Basic and Advance Measurements for a Fixed Target

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Mohammed Faisal; [2011]
    Keywords : Double Ridge Guide Horn Antenna; Global Backprojection GBP ; Ground-Based SAR GB-SAR ; Interferometry; Low loss-high frequency cable; Vector Network Analyzer VNA .;

    Abstract : Ground-Based Synthetic Aperture Radar (GB-SAR) system is a new innovative monitoring technique has been invented depending on the use of ground based applications and highly repeatable measurements. GB-SAR is a new class of SAR system based on unconventional platform like ground, building and ground vehicles that acts as a useful complement of airborne and spaceborne SAR system. READ MORE

  5. 10. 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
