—Current spaceborne radiometers do not achieve the required spatial resolution demanded by the scientific community due to antenna-size technological limitations. In recent years, several space agencies have been studying aperture synthesis interferometric radiometers as a way of overcoming these limitations , which are more evident at low microwave… (More)
(a) (b) Fig. 3. (a) Observation of " 00 change of ice slab on duraluminum mold at 13. the other hand, quick freezing may produce a specific distribution of salt concentration in ice volume. However, the main result of the measurements, as it follows from Figs. 2 and 3, is the hysteresis of " 00 in the case of slow-cycle temperature change for many days. Our… (More)
—The correlation between the visibility samples' noise of an aperture synthesis radiometer are required for the computation of the recovered temperature noise of a given pixel and of the improvement introduced by baseline redundance. A general expression for this correlation and noise examples for a linear array are presented.
