Electromagnetic scattering models for ocean remote sensing: Overview and guide to use

Several microwave sensors are currently employed to monitor the oceans. In order to obtain the desired information from these sensors´ data, models describing how sea state parameters are related to the backscattered signal are needed. This is achieved by electromagnetic scattering models based on reliable sea surface models. In this work, we review the main scattering models and suggest the proper one for each of the main sensors and marine applications.
