The Intertwined Factors Affecting Altimeter Sigma0
Remote SensingRadar 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 ...
