Estimation of Sea Wave Heights by Two-Frequency Cross-Correlation Function of Reflected Signals of a Spaceborne Radar Altimeter with Nadir Synthesis of Antenna Aperture

Abstract

In the work we introduce novel approach to remote sensing from space for the estimation of sea wave heights with a spaceborne high precision two-frequency radar altimeter with nadir synthesis antenna aperture. Experiments show considerable reduction of the decorrelation factor of the correlation coefficient and so significant enhancement of the sensitivity of the altimeter for the estimation for the sea wave status.
