Synthetic Aperture Radar Drone Gets Interferometric Imaging
7 hours ago
- Developed a more powerful autofocus algorithm to improve radar image clarity.
- Added an RTK-capable GPS receiver or uses PPK positioning for centimeter-level accuracy.
- Implemented hardware improvements including stabilizing the phase-locked loop and data compression.
- Extended software to create high-resolution interferometric images for elevation mapping.
- Flies the drone twice at different altitudes and compares phase data to generate detailed elevation maps.
