During the summer of 2009, the Characterization of Arctic Sea Ice Experiment 2009 (CASIE-09) operated a small, unmanned aircraft system (UAS) over the Arctic Ocean for a number of long-distance flights from Svalbard Island. In addition to other instruments, the UAS carried a small C-band synthetic aperture radar (SAR) known as MicroASAR to image sea ice roughness at 1 m resolution. This paper briefly...
The MicroASAR is a flexible, robust SAR system built on the successful legacy of the BYU μSAR. It is a compact LFM-CW SAR system designed for low-power operation on small, manned aircraft or UAS. The NASA SIERRA UAS was designed to test new instruments and support flight experiments. NASA used the MicroASAR on the SIERRA during a science field campaign in 2009 to study sea ice roughness and break-up...
