Polarimetric radar

From Glossary of Meteorology

polarimetric radar

A radar capable of measuring any or all of the polarization-dependent attributes of a target or backscattering medium.

The term may denote a radar capable of measuring the full polarization matrix by means of variable transmitted polarization and dual-channel reception. It may also denote a simpler radar that transmits a single polarization and receives separately the copolarized and cross-polarized components of the returned signal.
Compare dual-channel radar, dual-polarization radar, polarization-diversity radar.
