3D trajectory position error estimation autofocus, antenna pattern normalization, and polarimetric calibration for drone mounted SAR radar.

Introduction Radar drone. Since the first post I have added a Gopro camera and a second GPS for redundancy. Earlier this year I made a polarimetric synthetic aperture radar (SAR) mounted on a drone . I have since worked a lot on the software side to improve the image quality and now the same hardware can generate much better quality images. The main contribution of this article is description of a new SAR autofocus algorithm that combines some of the existing SAR autofocus algorithms to make an algorithm that is well-suited for drone mounted SAR. Also antenna pattern normalization and polarime
