  1. 1. Assessing the accuracy for area-based tree species classification using Sentinel-1 C-band SAR data

    University essay from SLU/Dept. of Forest Resource Management

    Author : Alberto Udali; [2019]
    Keywords : Sentinel-1; tree species; random forest; linear discrimi-nant analysis; classification;

    Abstract : Forest type (FTY) and tree species classification (SPP) over the Remn-ingstorp test site were performed using ground-based field observations and remote sensing data sources. The field inventory for the forest estate and for the surrounding natural reserve of Eahagen was carried out in 2016. READ MORE

  2. 2. Radio signal DOA estimation : Implementing radar signal direction estimation on an FPGA.

    University essay from Linköpings universitet/Datorteknik

    Author : Alfred Patriksson; [2019]
    Keywords : FPGA; DOA; Radar; Direction of Arrival; Monopulse; Amplitude Monopulse; Phase Monopulse;

    Abstract : This master’s thesis covers the design and implementation of a monopulse directionof arrival (DOA) estimation algorithm on an FPGA. The goal is to implement a complete system that is capable of estimating the bearing of an incident signal. READ MORE

  3. 3. Above-ground biomass estimation in boreal productive forests using Sentinel-1 data

    University essay from Stockholms universitet/Institutionen för naturgeografi

    Author : David Roc Roc; [2019]
    Keywords : synthetic aperture radar SAR ; backscatter intensity; InSAR; interferometric coherence; LIDAR; above-ground biomass; forestry;

    Abstract : Estimation of biomass has high importance for economic, ecologic and climatic reasons due to the multiple ecosystem services offered by forested landscapes. Measurements that are taken in the field incur personal and economic costs. Nevertheless, biomass surveying based on remote sensing techniques offer efficiency thanks to covering large areas.

  4. 4. Intradyne Signal Recovery and Equalization for Optical Satellite Links

    University essay from KTH/Rymd- och plasmafysik

    Author : Philip Conroy; [2017]
    Keywords : ;

    Abstract : An optical communication system employing intradyne reception withoffline digital signal processing for a geostationary satellite communicationscenario is presented. The digital signal processing is improvedvia the implementation and comparison of several timing recovery algorithms,and the inclusion of an equalization stage. READ MORE

  5. 5. Joint use of Sentinel-1 and Sentinel-2 for land cover classification : a machine learning approach

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Miguel Gumersindo Castro Gomez; [2017]
    Keywords : Random Forest; temporal series; Physical Geography and Ecosystem analysisoptical; GEM; land cover classification; SAR; Earth and Environmental Sciences;

    Abstract : Reliable information on land cover is required to assist and help in the decision-making process needed to face the environmental challenges society has to deal with due to climate change and other driving forces. Different methods can be used to gather this information but satellite earth observation techniques offer a suitable approach based on the coverage and type of data that are provided. READ MORE
