Abstract
This project focuses on the implementation of image processing software for a drone-based synthetic aperture radar (SAR) system. The drone-SAR system is under development by a student design team. The specific contributions in this thesis are two stages of software development. In the first part, to achieve a basic image formation function, we implemented and demonstrated backprojection imaging using radar data and global positioning system (GPS) data collected by the team. In the second part, we researched and implemented an autofocus algorithm, in order to generate high-resolution images in the inevitable presence of measurement errors greater than one-quarter wavelength.
