Proof of Concept of the Multi-frequency Along-track Interferometric SAR Ocean Wind Current Measurement Technique

Abstract

This work is to develop and test methods to estimate currents and wind direction from ATI SAR data at high-resolution (ideally, at the same resolution as the SAR image), and thereby provide a high-fidelity surface current information in littoral and riverine environments. Furthermore, these techniques will be developed using technology suitable for operation from UAVs.The specific objectives are to: Add an L-band and an X-band ATI SAR to our airborne platform; Collect multi-frequency ATI SAR data in a coastal environment where terrain and vegetation are likely to affect wind forcing on the water surface; Develop a retrieval algorithm to estimate both surface currents and wind direction within the domain imaged.
