1. 1. ISAR Imaging Enhancement Without High-Resolution Ground Truth

   University essay from Linköpings universitet/Datorseende

   Author : Moltas Enåkander; [2023]
   Keywords : SAR; SAR Imaging; ISAR; ISAR Imaging; Machine learning; Convolutional neural network; CNN; neural network; Super resolution; Unsupervised learning;

   Abstract : 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. 2. Exploring Near-Field SAR with mmWave Pulsed Coherent Radar

   University essay from Lunds universitet/Matematisk statistik

   Author : Elina Yrlid; [2023]
   Keywords : SAR; Synthetic Aperture Radar; PCR; pulsed coherent radar; radar; mmWave; millimeter-wave; near-field; 60GHz; Technology and Engineering;

   Abstract : This thesis explores the option to apply Synthetic Aperture Radar (SAR) techniques to image near-field targets utilizing mmWave pulsed coherent radar (PCR). The recent development of mmWave radars has broadened the scope for SAR, but there are few concrete examples explaining and demonstrating the fundamental SAR algorithms from a PCR perspective.

6. 5. Simulated SAR with GIS data and pose estimation using affine projection

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

   Author : Martin Divak; [2017]
   Keywords : ;

   Abstract : Pilots or autonomous aircraft need to know where they are in relation to the environment. On board aircraft there are inertial sensors that are prone to drift which requires corrections by referencing against known items, places, or signals. READ MORE
