Wavetank Scatterometry

 

Project: C-band (4-8 GHz) FMCW Radar System for Ocean Wave Scatterometry

UCSB Ocean Science Department
Funded by: U.S. Navy
Description: This work was aimed at developing an improved understanding of scattering mechanisms from breaking waves on a rough ocean, simulated with UCSB's Wave Tank system in the Ocean Science Department (directed by Prof. Marshall Tulin).  A bi-static FMCW radar (4-8 GHz) system with electro-mechanical polarization control (HH, HV, VH, VV) was developed and synchronized with a video capture system to pinpoint scattering events.   Measured data using this system, along with advanced modelling of breaking waves by Prof. Tulin's group, provided a compelling explanation for observed anomalously large and poliarization-dependent  scattering returns using a simple ray-tracing argument.
