Ocean Wave Height Retrieval Using Airborne Polarimetric Remote Sensing

Abstract

Accurate quantification of ocean waves is essential to defining the overall hydrodynamics of the upper ocean. However, existing methodsof remotely quantifying ocean waves over large spatial areas either present logistical difficulties or lack the ability to resolve the entirety ofspatial scales present in the wave field. A new approach using polarimetric cameras is developed and validated here. It is demonstrated thatby measuring the angle of polarization from reflected light from the ocean surface, the two-dimensional wave slope field can be determinedand then integrated to yield significant wave height. The impact of camera viewing angle and atmospheric path contributions on wave slope measurements are also demonstrated.
