Abstract

NEARSHORE OCEAN KINEMATICS AND STRUCTUES OBSERVED WITH UAV-SUITABLE REMOTE SENSING INSTRUMENTS

The Applied Physics Laboratory at the University of Washington has developed the Compact Airborne System for Imaging the Environment (CASIE). This system consists of a dual-beam along-track interferometric (ATI) synthetic aperture radar (SAR), two infrared and visible wavelength cameras, and a downward pointing lidar. The ATI SAR is capable of measuring two components of the surface velocity, from which surface current and wave parameters can be estimated. The infrared cameras can be configured as nadir-pointed cameras to measure very small changes in surface temperature, so fronts and mixing of different bodies of water are visible. When the cameras are tilted, they form a wide field-of-view image and can image surface gravity waves and internal waves, while maintaining sensitivity to surface temperature differences. While the equipment is mounted on a Cessna 172 aircraft, almost all of the sensors that make up the system have either been flown on, or are suitable for installation on an unmanned aerial vehicle (UAV). In this paper, we demonstrate the capability of this system by showing multi-sensor observations of ocean waves, estuarine fronts, and internal waves.
