In 2009 BYU flew a microASAR as part of the CASIE experiment on a Sierra UAV over the Arctic Ocean north of Svalbard Island [1]. Over 17 hours of data were collected at resolution of better than 1 m and a swath with of 1 km. The radar was right-looking and due to the low alittude images span from 0 deg incidence angle at near-swath to over 85 deg at far swath.The aircraft flew long transects out to the edge of the sea ice, then flew "racetrack" patterns over the Marginal Ice Zone.

Here we provide a few image examples in KMZ form suitable for viewing in GoogleEarth. Some of these images overlap. Details of the processing are given in [2]. Note that these are uncalibrated images and that no gain correction for aircraft roll has been applied. A sample of raw SAR data can be obtained from this link.
