Lessons learned from SIR-C calibration

In this paper, lessons learned through the calibration of SIR-C data will be reviewed in the context of upcoming spaceborne, polarimetric SAR missions planned for launch later in this decade.

Polarized light from star forming regions

Studies of polarized radiation from molecular clouds and the environments of protostars are providing information about the orientations and strengths of magnetic fields and the sizes andcompositions of dust grains in these environments.

Polarimetric Confirmation of the Dust Disk Around BD+31 643

We show that the geometry of the polarization can be understood in terms of multiple scattering within an optically thick disk, yielding the observed polarization parallel to the long axis of the observed edge-on disk.

Polarimetric and Interferometric SAR Calibration Verification Methods

It is necessary to calibrate SAR data in order to use the data for science applications. When both polarimetric and interferometric data are collected simultaneously, these SAR data can be used for cross-calibration and verification.
