Multi-Mission Cross-Calibration of Satellite Altimeters: Constructing a Long-Term Data Record for Global and Regional Sea Level Change Studies

open access: yesRemote Sensing, 2014
Climate studies require long data records extending the lifetime of a single remote sensing satellite mission. Precise satellite altimetry exploring global and regional evolution of the sea level has now completed a two decade data record.

A Signal Matching Method of In-Orbit Calibration of Altimeter in Tracking Mode Based on Transponder

open access: yesRemote Sensing
In this paper, a matching method for altimeter and transponder signals in Sub-optimal Maximum Likelihood Estimate (SMLE) tracking mode is proposed. In the in-orbit calibration of the altimeter in SMLE tracking mode using the reconstructive transponder ...

The Intertwined Factors Affecting Altimeter Sigma0

open access: yesRemote Sensing
Radar altimeters receive radio-wave reflections from nadir and determine surface parameters from the strength and shape of the return signal. Over the oceans, the strength of the return, termed sigma0 (σ0), is strongly related to the small-scale ...
