Interoperability and compatibility techniques for Counter Radio controlled IED Electronic Warfare (CREW) and other Radio Frequency Communication

The simultaneous need for blue force broadband communications link and the proliferation of sensitive SIGINT receivers has created the need for the US Navy to develop a system capable of suppressing broadband interference in close proximity to sensitive receivers. The goal of the current SBIR is to develop a low cost system that will provide the US Navy with the capability to deploy and use a variety of transmitters, communication systems, and SIGINT systems in close proximity without the requirement of connecting the various systems. A wideband interference rejecting antenna system must provide broadband omni-directional coverage when installed on a vehicle and be capable of maximum wideband interference cancellation. The system must operate over a minimum frequency range of today’s existing terrestrial SIGINT and communications systems. Finally, the system must be capable of rejecting both on-vehicle and in-convoy interference sources. The FIRST RF team proposes a new system that combines broadband antenna technology and advanced null forming techniques with state of the art cancellation electronics to provide a wideband wireless cancellation technology to meet the US Navy requirements.
