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 rymdteknikAbstract : 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

2. ISAR Imaging Enhancement Without High-Resolution Ground Truth
University essay from Linköpings universitet/DatorseendeAbstract : In synthetic aperture radar (SAR) and inverse synthetic aperture radar (ISAR), an imaging radar emits electromagnetic waves of varying frequencies towards a target and the backscattered waves are collected. By either moving the radar antenna or rotating the target and combining the collected waves, a much longer synthetic aperture can be created. READ MORE

3. Arbitrary motion Synthetic Aperture Radar
University essay from Lunds universitet/Matematisk statistikAbstract : Syftet med denna avhandling är att utveckla en ny metod för att producera bilder med syntetisk aperturradar (SAR), med utgångspunkt i scenarier med arbiträr rörelse vad gäller radarsensorn. SAR är en väletablerad metod för att skapa 2- eller 3-dimensionella radarbilder, som traditionellt sett antar att radar-sensorns rörelse är linjär och förutsägbar. READ MORE

4. Analysis of radio surveillance in search of missing persons - An empirical study of Bluetooth Low Energy and Wi-Fi characteristics
University essay from Linköpings universitet/Kommunikations- och transportsystem; Linköpings universitet/Tekniska fakultetenAbstract : Development of technical and methodological support has been identified as a key area for future research and development within the search and rescue (SAR) of missing persons in Sweden. Previous studies have demonstrated the feasibility of using Wi-Fi signals to locate a missing person, and also developed hardware and software for SAR systems based around Unmanned Aerial Vehicles (UAV).

5. Whole-body SAR measurements of 5G mmW base stations in a reverberation chamber
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : This study presents a method for measurement of whole-body average specific absorption rate (WBSAR) of a millimeter wave (mmWave) antenna in a reverberation chamber. The method takes advantage of multiple radiated power measurements to estimate the power absorbed in a phantom placed in front of the antenna. READ MORE
