   University essay from Lunds universitet/Matematik LTH

   Author : John Backsund; Anton Samuelsson; [2022]
   Keywords : reinforcement learning; UAV; machine learning; policy gradient; artificial intelligence; reinforce; Technology and Engineering;

   Abstract : With an increased amount and availability of unmanned aerial vehicles (UAVs) and other remote sensing devices (e.g. satellites) we have recently seen an explosion in computer vision methodologies tailored towards processing and understanding aerial view data. READ MORE

3. 2. Creating a semantic segmentationmachine learning model for sea icedetection on radar images to study theThwaites region

   University essay from Luleå tekniska universitet/Rymdteknik

   Author : Carmen Fuentes Soria; [2022]
   Keywords : Synthetic Aperture Radar SAR ; Machine Learning ML ; Semantic segmentation; Convolutional Neural Networks CNN ; Thwaites Glacier;

   Abstract : This thesis presents a deep learning tool able to identify ice in radar images fromthe sea-ice environment of the Twhaites glacier outlet. The project is motivatedby the threatening situation of the Thwaites glacier that has been increasingits mass loss rate during the last decade. READ MORE

   Abstract : Millimeter-wave radar imaging has potential uses in applications such as material analysis and medical in-vivo scanning of tissue. This thesis is about measuring objects using a millimeter wave radar, implement radar imaging algorithms and evaluate the resulting images. READ MORE

5. 4. Experiment with Moving Target Focusing using GB-SAR

   University essay from Blekinge Tekniska Högskola/Institutionen för tillämpad signalbehandling

   Author : Krishna Mani Bajagain; [2014]
   Keywords : SAR; GB-SAR; GBP algorithm; Moving target Detection;

   Abstract : Ground Based Synthetic Aperture Radar (GB-SAR) refers to SAR system which is mounted on ground linear track. It works on same principle as conventional SAR. Nowadays GB-SAR plays prominent role in the studies of many natural phenomenon as well as in studying some artificial infrastructure or terrain. READ MORE

6. 5. An Evaluation of Interpolation and Oversampling Effects on Image Quality in Synthetic Aperture Radar Processing with Global Back-projection

   University essay from Blekinge Tekniska Högskola/Institutionen för tillämpad signalbehandling

   Author : Andreas Hartman; [2014]
   Keywords : Synthetic Aperture Radar; Global Back-projection; Image Quality; Side Lobe Suppression;

   Abstract : For time domain SAR processing algorithms, such as Global Back-projection, interpolation becomes a part of the implementation. In order for the interpolation to yield good results, the oversampling rate used in the sampling of the original data may constitute an important factor. READ MORE
