  1. 6. Enhancement of SAR Image Resolution with Implementation of Circular GB-SAR System

    Master-uppsats, Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Författare :Dheeraj Nehru Neravati; [2013]
    Nyckelord :Synthetic Aperture Radar; UWB; GB-SAR; Circular SAR; Circular Aperture; Resolution; Enhancement; Radar; GBP;

    Sammanfattning : Radars were used for surveillance and remote sensing but nowadays they handle a vast range of applications, radar imagery being one of them. The need for high resolution images was inevitable which lead to Synthetic Aperture Radar (SAR) systems. SAR plays a prominent role in remote sensing applications and geophysical studies. LÄS MER

  3. 7. 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. 8. Development of an Ultra Wide-Band(UWB) Synthetic Aperture Radar (SAR)System for Imaging of Near Field Object

    Master-uppsats, Institutionen för tillämpad fysik och elektronik

    Författare :Seyedeh shaghayegh Fayazi; [2012]
    Nyckelord :Bow Tie Antenna; Ultra Wideband UWB ; Synthetic Aperture Radar SAR ; Direction of Arrival DOA .;

    Sammanfattning : Ultra-wideband (UWB) technology and its use in imaging and sensing have drawnsignicant interest in the last two decades. Extensive studies have contributed toutilize UWB transient scattering for automated target recognition and imagingpurposes. In this thesis a near-eld UWB synthetic aperture radar (SAR) imagingalgorithm is presented. LÄS MER

  5. 9. 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

  7. 10. Oil Well Monitoring by Ultra-wideband Ground Penetrating Synthetic Aperture Radar

    Master-uppsats, Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

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

    Sammanfattning : 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. LÄS MER
