  1. 1. A CONCEPT STUDY OVER A RADAR-BASED TERRAIN AWARENESS SYSTEM (RTAS)

    Master-uppsats, Mälardalens universitet/Akademin för innovation, design och teknik

    Författare :Rawand Alostaz; [2024]
    Nyckelord :RADAR; SAAB; Safety; Aviation; Safety-Critical;

    Sammanfattning : .... LÄS MER

  3. 2. Real-Time Navigation for Swarms of Synthetic Aperture Radar (SAR) Satellites

    Master-uppsats, Luleå tekniska universitet/Rymdteknik

    Författare :Antoni Eritja Olivella; [2024]
    Nyckelord :SAR; Real-time orbit determination; Real-time baseline determination; swarms; satellite; formation flying;

    Sammanfattning : The pursuit of precision and flexibility in satellite missions has led to an increased number of formation flying missions being developed. These systems consist of multiple satellites flying at close distances (from a few kilometres to a few meters) to achieve common objectives. LÄS MER

  4. 3. Detection and Analysis of Anomalies in Tactical Sensor Systems through Structured Hypothesis Testing

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Fredrik Ohlson; [2023]
    Nyckelord :Tactical sensor systems; Sensor fusion; Model based diagnostics; Hypothesis testing; Taktiska sensor system; Sensor fusion; Modellbaserad diagnostisering; Hypotesprövning;

    Sammanfattning : The project explores the domain of tactical sensor systems, focusing on SAAB Gripen’s sensor technologies such as radar, RWR (Radar Warning Receiver), and IRST (InfraRed Search and Track). The study employs structured hypothesis testing and model based diagnostics to examine the effectiveness of identifying and isolating deviations within these systems. LÄS MER

  5. 4. Robust Aircraft Positioning using Signals of Opportunity with Direction of Arrival

    Master-uppsats, Linköpings universitet/Reglerteknik

    Författare :Erik Axelsson; Sebastian Fagerstedt; [2023]
    Nyckelord :Simultaneous localisation and mapping; direction of arrival; signals of opportunity; extended Kalman filter; positioning;

    Sammanfattning : This thesis considers the problem of using signals of opportunity (SOO) with known direction of arrival (DOA) for aircraft positioning. SOO is a collective name for a wide range of signals not intended for navigation but which can be intercepted by the radar warning system on an aircraft. LÄS MER

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

    Master-uppsats, Luleå tekniska universitet/Institutionen för system- och rymdteknik

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

    Sammanfattning : 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. LÄS MER
