Wow, stepped-frequency synthetic radar imaging using FFTs... I never thought I'd see that on HN... My PhD and PostDoc were on SAR and ISAR imaging, doing maximum likelihood phase corrections before the FFTs to reduce motion blur. I was sponsored by the Australian Defence Science and Technology Organisation. My summer holidays were at the Edinburgh airforce base near Adelaide, with a van full of radar gear snapping stepped-frequency radar reflections from aircraft coming in to land.
