  1. 1. Development and Implementation of Techniques for the Simulation and Processing for Future SAR Systems

    University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Author : Tim Kinnunen; [2023]
    Keywords : Synthetic Aperture Radar; SAR; Reverse Backprojection Algorithm; RBPA; Backprojection Algorithm; SAR simulator; SAR processing;

    Abstract : Synthetic Aperture Radar (SAR) is a type of radar system that can generate high-resolution images with which one can detect subtle changes on the scale of centimetres from space. It can operate in any weather condition and during both day and night, making it unique compared to optical sensors. READ MORE

  3. 2. Data-Driven Reachability Analysis of Pedestrians Using Behavior Modes : Reducing the Conservativeness in Data-Driven Pedestrian Predictions by Incorporating Their Behavior

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : August Söderlund; [2023]
    Keywords : Data-driven reachability analysis; Autonomous vehicles; Automated safety; Autonomous situational awareness; Datadriven nåbarhetsanalys; Autonoma fordon; Automatiserad säkerhet; Autonom situationsmedvetenhet;

    Abstract : Predicting the future state occupancies of pedestrians in urban scenarios is a challenging task, especially considering that conventional methods need an explicit model of the system, hence introducing data-driven reachability analysis. Data-driven reachability analysis uses data, inherently produced by an unknown system, to perform future state predictions using sets, generally represented by zonotopes. READ MORE

  4. 3. Impact of C-ITS on Mobility and Society

    University essay from KTH/Transportplanering

    Author : Ninnie Tägtström; [2023]
    Keywords : C-ITS; ITS; Mobility; Digitization; Automation; Transportation System; Traffic Signals; Vensim;

    Abstract : This thesis investigates the important potential of Cooperative Intelligent Transport Systems (C-ITS) onmobility and society. C-ITS appears as a promising solution to reinvent transportation and become avital part of the ever-evolving environment as developments in technology continue to change the world. READ MORE

  5. 4. Real Time Navigation Algorithms for LEO Small Satellites using COTS GNSS

    University essay from KTH/Lantmäteri – fastighetsvetenskap och geodesi

    Author : Nathan Groisne; [2023]
    Keywords : PNT; Small Satellite; COTS; GNSS; Navigation; ACS; PNT; små satelliter; COTS; GNSS; navigering; ACS;

    Abstract : Many satellites in LEO use a GNSS-based navigation system, taking advantage of the GNSS constellations in MEO to enhance navigation capabilities. The thesis work focused on developing the software enabling GNSS-based navigation for Hemeria's future small satellites operating in LEO. READ MORE

  6. 5. Implementation of Flight Mechanical Evaluation Criteria in an Aircraft Conceptual Design Tool with focus on Longitudinal Motions

    University essay from Linköpings universitet/Fluida och mekatroniska system
