It refers to the orientation of the electric field in a wave—typically horizontal ( ) or vertical (
The true power of this technology lies in its ability to differentiate between complex environments that look identical to standard sensors. Polarimetric Radar Imaging: From Basics to Applications
) channels of a digital camera, but for physical properties.
These systems, often called quad-pol , transmit and receive in both orientations. This results in four data channels ( HHcap H cap H VVcap V cap V HVcap H cap V VHcap V cap H ), which act like the Red, Green, and Blue ( RGBcap R cap G cap B
