The Navy battle group relies on the successful functioning of antenna systems to meet mission requirements. Numerous antennas are all competing for a portion of the rf spectrum and for a clear field of view. Topside space to allow undegraded operation of the antenna systems is not available on any Navy ship. A reduction in the quantity of individual antennas without reducing the quality of the service provided is needed. Chu Associates, Inc. proposes to develop novel innovative antenna techniques and design approaches to reduce the quantity of antennas, improve performance characteristics lessen system interaction, and improve survivability and reliability.
