  1. 1. Contribution to the Understanding of the Effects of Propagation through the Ionosphere of P-band SAR Data

    Master-uppsats, Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Författare :Johannes Samuel Erland Rönner; [2023]
    Nyckelord :Synthetic aperture radar; Ionosphere;

    Sammanfattning : The BIOMASS mission from the European Space Agency (ESA) is designed to measurebiomass and carbon content in Earth’s forests. To account for phase changes caused byionospheric variations, a map-drift autofocus algorithm is developed, which utilises a phasescreen of the ionosphere to eliminate phase errors in the signal.

  3. 2. Usability of Sentinel-1 C-band VV and VH SAR data for the detection of flooded oil palm

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Sarah Lee Sienaert; [2023]
    Nyckelord :Geography; GIS; Sentinel-1; SAR; C-band; VV; VH; Oil Palm; Flood; Earth and Environmental Sciences;

    Sammanfattning : Flooding in oil palm plantations in Southeast Asia is a common problem. The oil palm’s habitable range is restricted to lowland equatorial areas, and the high rainfall and degraded landscapes associated with oil palm cultivation leaves oil palm prone to flooding. LÄS MER

  4. 3. Towards the Performance Assessment of aMapdrift Autofocus for a P-Band SARMission Implementation

    Master-uppsats, Luleå tekniska universitet/Rymdteknik

    Författare :Andrés Felipe Betancourt Payán; [2019]
    Nyckelord :SAR; Autofocus; P-Band; Biomass;

    Sammanfattning : In the context of the ESA BIOMASS mission in which for the first time, a P-Band SAR sensor isgoing to be mounted into a spaceborne system. With its penetration capability, it will contributeto the measurement of the biomass and carbon content in the Earth’s forests. LÄS MER
