Color-coded radar scattering imagery (UAVSAR, Pauli)

UAVSAR_POLSAR_PAULI
deformation NASA ASF Level 1 active
In plain English

What it measures. Color-coded radar imagery that highlights different ways the land surface bounces radar signals back, using a method called Pauli decomposition. Different colors flag different physical structures on the ground.

How it's made. Generated from NASA's UAVSAR radar flown on a G-III aircraft, with the radar returns mathematically decomposed to separate distinct scattering types.

How & where you'd use it. Helps interpret what's on the surface, such as bare ground, vegetation, or built structures, by their radar signatures. It's a specialized input mostly used by radar analysts.
