  1. 1. Global Backprojection for Imaging of Targets Using M-sequence UWB radar system

    Master-uppsats, Akademin för teknik och miljö

    Författare :Madhava Reddy Kota; Binod Shrestha; [2013]
    Nyckelord :: Synthetic Aperture Radar; Time domain algorithm; Back projection algorithm; Ultra Wide-beam; M-sequence; SAR Image processing; UWB radars with M-sequence.;

    Sammanfattning : Synthetic Aperture Radar (SAR) is an emerging technique in remote sensing. The technology is capable of producing high-resolution images of the earth surface in all-weather conditions. LÄS MER

  3. 2. SAR imaging with a hand-held UWB radar system

    Magister-uppsats, Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Författare :Alexander Rajula; [2012]
    Nyckelord :handheld; imaging; radar; SAR;

    Sammanfattning : Synthetic aperture radar (SAR) systems are used extensively for imaging vast areas using electromagnetic radiation. Radar systems have the benefit of being able to image areas which optical light cannot pass through, which makes them suitable for surveillance and weather monitoring, or monitoring through difficult atmospheric conditions.

  4. 3. Fast Back Projection Algorithm for Bi-Static SAR Using Polar Coordinates

    Master-uppsats, Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Författare :Omer Elhag; [2012]
    Nyckelord :Bi-static SAR; Fast Backprojection; Global Backprojection; monostatic SAR; SAR image processing; Synthetic Aperture Radar; time domain algorithms; Ultra Wide-beam; UWB Bistatic SAR.;

    Sammanfattning : Synthetic Aperture Radar (SAR) plays a significant role in geophysical studies and remote sensing applications. SAR inherits the benefits of imaging RADAR over the other optical sensors such as working in all weather conditions and working independently of sunlight. LÄS MER

  5. 4. 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

  7. 5. 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.
