19 GHz space-Earth depolarization measurements at 4° polarization

Depolarization was measured at a polarization angle of
4\deg
from vertical. Depolarization transformed to this
4\deg
polarization from measurements made at polarizations
21\deg
from vertical and horizontal is compared with the direct measurements scaled to the path elevation angle of the transformed measurements. Over the ranges of attenuation and depolarization for which the measurements are meaningful, the agreement between them is good. These results further reinforce our confidence in the results and conclusions obtained earlier using the polarization transformation technique.
