It appears feasible for satellite relay systems to provide polarization discrimination of 20 to 30 dB (or more with adaptive antennas) in the antenna main beam. Thus if the systems are designed to operate with smaller wanted to unwanted signal ratios than those provided by polarization discrimination, it should be possible to double the effective spectrum available by using it independently on two orthogonal polarizations. 9 pp. Ref.

The paper was a product of the RAND Corporation from 1948 to 2003 that captured speeches, memorials, and derivative research, usually prepared on authors' own time and meant to be the scholarly or scientific contribution of individual authors to their professional fields. Papers were less formal than reports and did not require rigorous peer review.
