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

   University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

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

   Abstract : 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. READ MORE

3. 2. Spatial Variability in the Ionosphere and GNSS Signal Delays in the L-band: A Direct Comparison of In-Situ Satellite- and Swepos-Data

   University essay from Uppsala universitet/Institutionen för fysik och astronomi; Uppsala universitet/Institutet för rymdfysik, Uppsalaavdelningen

   Author : Oscar Suneson; [2021]
   Keywords : fysik; jonosfären; GNSS; GPS; astrofysik; navigationssystem; mätteknik;

   Abstract : It has been shown that ionospheric irregularities can disturb our GNSS (Global Navigation Satellite System) communication. This disturbance is caused by scintillation of the radio signals when they pass through the ionosphere, leading to lock-on difficulties or in worst case, a loss of position for the GNSS-receiver.

4. 3. Design and Test of an L-Band (GNSS) Low Noise Amplifier and Limiter

   University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

   Author : Ms Navneeta; [2015]
   Keywords : Technology and Engineering;

   Abstract : Abstract This thesis work was performed at RUAG Space AB, Göteborg, Sweden. The aim of this thesis is to test the performance boundaries of SiGe based heterojunction bipolar transistor in designing a low noise amplifier meant for GNSS applications. READ MORE

5. 4. Comparison and Fusion of space borne L-, C- and X- Band SAR Images for Damage Identification in the 2008 Sichuan Earthquake

   University essay from KTH/Geodesi och geoinformatik

   Author : SIN WAI LAU; [2011]
   Keywords : Remote sensing; SAR; image fusion; Sichuan earthquake; PALSAR; RADARSAT-1; TerraSAR-X;

   Abstract : Remote sensing has been widely used in disaster management. However, application of optical imageries in damage detection is not always feasible for immediate damage assessment. In the case of the Sichuan earthquake in 2008, the damaged areas were covered by cloud and fog for most of the time. READ MORE

6. 5. Mapping of Floodplains in the Atankwidi River Basin

   University essay from Lunds universitet/Avdelningen för Teknisk vattenresurslära

   Author : Andrej Nikolaev; [2010]
   Keywords : Idrisi; C-band; L-band; Atankwidi; mapping of floodplains; SOBEK; Technology and Engineering;

   Abstract : The Atankwidi River Basin is situated in the Upper East Region of Ghana. The Basin has an area of around 275 km2. The semiarid climate in which the Atankwidi is situated is characterized by one rainy season spanning from April to September and one dry season spanning from September to April. READ MORE
