  1. 1. Doppler radar odometry for localization in difficult underground environment

    University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

    Author : Emil Fritz; Annika Nilsson; [2023]
    Keywords : SLAM; Localization; Mappers; Odometry; Drift; RIO; Radar; Lidar; IMU;

    Abstract : Accurate and efficient localization is a fundamental requirement for autonomous operation of robots, especially in areas that deny global navigation services. Localization is even more challenging in environments that present visual and geographic difficulties. READ MORE

  2. 2. Characterisation of Low-Level Jets and their Influence on Low-Level Clouds over the Baltic Sea; Östergarnsholm Observatory, Sweden

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Förbränningsfysik

    Author : Johan Lundberg; [2021]
    Keywords : Low-level jets; Low-level clouds; LLJs; LLCs; Boundary layer; ABL; CBH; Lidar; Ceilometer; Turbulent intensity; Physics and Astronomy;

    Abstract : In this study, about two years of data from Östergarnsholm in the Baltic Sea are used to analyse offshore low-level clouds (LLCs) influenced by low-level jets (LLJs) in the marine atmospheric boundary layer. The LLJs are passages of strong horizontal winds near the surface and are measured using a Doppler LiDAR, which provides information about the wind speed and wind direction up to 300 meters.

  3. 3. Determination of an Optimum Sector Size for Plan Position Indicator Measurements using a Long Range Coherent Scanning Atmospheric Doppler LiDAR

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Elliot Simon; [2015]
    Keywords : LiDAR; WindScanner; PPI; Sector Scan; Dual Doppler; Remote Sensing; Wind Measurement;

    Abstract : As wind energy plants continue to grow in size and complexity, advanced measurement technologies such as scanning Doppler LiDAR are essential for assessing site conditions and prospecting new development areas.   The RUNE project was initiated to determine best practices for the use of scanning LiDARs in resource assessments for near shore wind farms.

  4. 4. Turbine-Mounted Lidar:The pulsed lidar as a reliable alternative.

    University essay from Institutionen för kultur, energi och miljö

    Author : Isaac Braña; [2011]
    Keywords : Wind power; doppler lidar; pulsed lidar; continuous-wave lidar; power control system; wind turbine-mounted lidar.;

    Abstract : Expectations for turbine-mounted lidar are increasing. The installation of lidars in wind turbine nacelles for measuring incoming winds, preventing wind gusts and increasing energy productions is after recently studies, technically and economically feasible. READ MORE
