Inspired by the synthetic aperture radar (SAR) technique, a nadir radar altimeter concept
called the “Delay/Doppler altimeter” or “SAR mode altimeter” provides better precision and …

Cryosat-2 is the first satellite that embarks an altimeter able to operate in several modes.
Among them, the Synthetic Aperture Radar mode (SARM) also referred to as Delay Doppler …

The retrieval of the three geophysical parameters–sea surface height above the reference
ellipsoid (SSH), significant wave height (SWH) and wind speed at 10 m above the sea …

Cryosat-2 was designed for its primary scientific objectives, ie for cryosphere science. As far
as oceanography is concerned, various mission design choices make it less accurate than …

SAR altimetry is a new high-resolution operation mode exploited in new-generation
altimeter missions, such as Sentinel-3. It takes advantage of its enhanced along-track …

In this paper, we introduce the concept, develop the theory, and demonstrate the
advantages of fully focused coherent processing of pulse echoes from a nadir-looking pulse …

The precision of sea-surface (or ice-surface) height measurements by radar altimetry
improves in direct proportion to the square root of the number of statistically independent …

In this paper we derive a closed-form solution to generate a backscatter power
representation for both unfocused synthetic aperture radar altimetry and conventional …

The Water Inclination Topography and Technology Experiment (WITTEX) consists of three
TOPEX-class radar altimeters on individual satellites in the same orbit plane. If built with …

This paper describes an innovative method for processing nadir altimeter data acquired in
Synthetic Aperture Radar (SAR) mode, enhancing the system performances over open …
