| Abstract | The application potential of compact polarimetry is assessed for lake and river ice monitoring. Initial investigations focus on freeze-up identification for study areas in the Canadian Arctic.
RADARSAT-2 quad-polarized imagery is used to simulate compact polarized imagery of a type that will be available from the RADARSAT Constellation Mission. Compact polarimetry parameters are compared with standard linear co- and cross-polarized
parameters, and with polarimetric decomposition parameters. The relative information content and ice/water discrimination potential of the parameters are discussed. Preliminary results indicate that circular-linear and circular-circular parameters
from compact polarimetry are very similar to linear co- and cross-polarized parameters from RADARSAT-2 quad-polarized imagery. Indications are that compact polarimetry provides comparable information content and ice/water discrimination ability to
quad-polarized data. This work is part of the Remote Sensing Science Program of the Earth Sciences Sector, Natural Resources Canada. It is financially supported, in part, by the Canadian Space Agency. Parks Canada Agency and Environment Canada are
the projected primary end users, as well as research partners. |
