1. 1. 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

3. 2. Deinterleaving pulse trains with DBSCAN and FART

   Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Avdelningen för systemteknik

   Författare :Shad Mahmod; [2019]
   Nyckelord :DBSCAN; FART; Fuzzy; Adaptive; Resonance; Theory; Radar; Clustering; Deinterleaving; Machine Learning;

   Sammanfattning : Studying radar pulses and looking for certain patterns is critical in order to assess the threat level of the environment around an antenna. In order to study the electromagnetic pulses emitted from a certain radar, one must first register and identify these pulses. LÄS MER

4. 3. Flow simulation in MIKE URBAN based on high-resolution X-band radar data

   Master-uppsats, Lunds universitet/Avdelningen för Teknisk vattenresurslära

   Författare :Lisa Olsson; [2019]
   Nyckelord :X-band radar; MIKE URBAN; modelling; rainfall-runoff; online control; Technology and Engineering;

   Sammanfattning : Radar har använts sedan 1940-talet för att mäta och övervaka nederbörd. Under de senaste åren har X-bandradarn visat sig vara ett verktyg som kan förbättra indata till avrinningsmodellering inom urbana avrinningsområden. Detta tack vare sin höga upplösning i tid och rum jämfört med andra radarer som används vid nederbördsmätning. LÄS MER
