What is co-polarization?

Answer 1

Analysis of circular polarization (CP) utilizes two independent, orthogonal, components: right- and left-hand circular (RHC and LHC). The desirable component, having the intended sence of rotation (right, or left), is called the copolarization component. The undesirable component, with the opposite polarization, is called the crosspolarization component. The mix of copolarization and crosspolarization components determine the quality of CP and

correlates with the axial ratio.

Answer 2

Co-polarization refers to the arrangement where the electric field vectors of two waves are parallel to each other. In radar and remote sensing, co-polarization is used to describe the same polarization of the transmitted and received signals. This helps in maximizing the signal strength and reducing interference from noise and other sources.
