  5. 24. Enhancement of SAR Image Resolution with Implementation of Circular GB-SAR System

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

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

    Abstract : 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. READ MORE

  6. 25. Equivalent Dynamics Model of Ballasted Track Bed

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap
