Precision polarized bandwidth expansion

The Armed Forces has a long standing requirement for a robust global communications infrastructure to support real time operations. The bandwidth elasticity continues to be tested as demand continues to grow in support of multiple theater events. The US Army CERDEC Space and Terrestrial Communications Directorate, coupled with the US Navy is doing relevant research and development in order to expand the boundaries within the physics that govern bandwidth usage today. Such bandwidth economizing will aid systems being developed in support of both MILSATCOM and commercial frequency bands at the data rates required to support the battlefield. High speed digitization coupled with carrier code identifiers will be used to achieve usage beyond the conventional means of operation. In the development of polarizing with precision, multiple sampling techniques at various frequency domains will be evaluated for best suited applications. The US Army CERDEC SATCOM laboratories located at Aberdeen Proving Ground, MD is working with the US Navy and industry to evaluate and determine the most effective approach in expanding polarization techniques. The focus of testing will primarily consist of data recovery with signals of interest operating on the same frequency in three or more different polarizations simultaneously. Results from such testing will be used to effect polarizing with precision and determine the predictability using discriminate line of site and long haul applications. Functional variables will include angle of arrival, geographical origin of emission versus destination of delivery. Discussions will be principally focused on accomplishing data recovery using multi variant polarization techniques.
