Cosite Interference (Antenna Coupling) Management Technology for Airborne Communication Systems

Development of a modern airborne cosite interference management system for Navy aircraft is proposed. The development will involve a generalized analysis to quantify the benefits of various cosite interference mitigation technologies and to providerecommendations for their usage and their specifications. The results of this general analysis will be applied to a candidate cosite system suite on a target aircraft selected by NAVAIR as preparation for implementation in Phase II. A Phase I Optionprogram is proposed to: measure interantenna coupling conditions on a targeted aircraft, and to design the prototype system to be implemented in Phase II. The results of this program will provide the Navy with a blueprint for the management of cositeinterference on its airborne platforms for legacy VHF and UHF radios as well as the new JTRS radios. This enabling system will help fleet aircraft overcome mission-limiting cosite radio interference.
