Multiparameter radar

From Glossary of Meteorology

multiparameter radar

A radar capable of deriving more than one quantity from observations of a target. In meteorological applications, the term is usually applied to radars capable of measuring either 1) reflectivity and at least one polarization-dependent quantity, or 2) reflectivity and at least one wavelength-dependent quantity.

The term is not ordinarily applied to radars that operate with a single wavelength and measure only reflectivity and Doppler velocity.
Compare polarimetric radar.
