In SAR applications, the ionosphere is normally considered as a disturbance that has to be removed or compensated for. In this paper the ionosphere is the objective of observation. This is motivated by the fact that nowadays polarimetric SAR systems can provide high resolution ionospheric maps that are not possible using conventional ionospheric mapping tools. This paper investigates a set of new ionospheric parameters that can be observed and mapped by SAR by exploring range and azimuth sub-bands. The range sub-bands are used to estimate the ionosphere independently of polarimetry. The azimuth sub-bands are related to the three-dimensional geometry of the ionosphere, as well as, to its dynamic component. The potential to estimate these parameters from SAR sub-bands is discussed and first results using ALOS PALSAR data are presented.
