An introduction to microwave remote sensing of the asian seas

Abstract

In this chapter passive and active microwave sensors are introduced, their basic measurement principles are described, and few examples of microwave (MW) remote sensing of the Asian Seas are given. The space-borne sensors under consideration are MW radiometer, altimeter, scatterometer, and synthetic aperture radar (SAR). It is demonstrated that changes in the sea surface roughness can be used to infer ocean surface vector wind fields, but also that this roughness may depend on other parameters such as SST, waves and currents.
