摘要

Abstract

A new model is proposed to estimate the significant wave heights with ERS-1/2 scatterometer data. The results show that the relationship between wave parameters and radar backscattering cross section is similar to that between wind and the radar backscattering cross section. Therefore

the relationship between significant wave height and the radar backscattering cross section is established with a neural network algorithm

which is

if the average wave period is ≤7s

the root mean square of significant wave height retrieved from ERS-1/2 data is 0.51 m

or 0.72 m if it is >7s otherwise.
