Deep Image Prior Amplitude SAR Image Anonymization
Synthetic Aperture Radar images are a powerful tool for studying the Earth’s surface. They are radar signals generated by an imaging system mounted on a platform such as an aircraft or satellite. As the platform moves, the system emits sequentially high-power electromagnetic waves through its antenna.
