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

    Master-uppsats, Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

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

    Sammanfattning : 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. LÄS MER

    Master-uppsats, Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Författare :Ahmed Hamza Ibrahim Makki; [2010]
    Nyckelord :Bi-static SAR; monostatic SAR; GBP; C A code.;

    Sammanfattning : Synthetic Aperture Radar (SAR) is used to generate a high resolution radar image from low resolution aperture data. Different SAR configurations can be obtained. The research on the fixed receiver Bi-static SAR is still on its early stages and it is an interesting research hotspot. LÄS MER

  4. 8. RFI Suppression in Low Frequency UWB SAR Using the RLS Algorithm

    Master-uppsats, Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

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

    Sammanfattning : 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.

  5. 9. Synthetic Aperture Radar Image Quality Measurements

    Master-uppsats, Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

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

    Sammanfattning : 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). LÄS MER
