Satellite communication (SATCOM) systems need to operate in challenging and hostile radio frequency (RF) environments in the presence of unintended and/or intended RF interferences (RFI). For military and commercial applications, it is important to develop advanced RFI mitigation and anti-jamming (AJ) capabilities. Key enabling technologies for such capabilities include advanced RF situation awareness and adaptive dynamic resource allocation (DRA).

The Intelligent Fusion Technology, Inc. (IFT) team has developed EDGES, an Electronic Defense Game-Theoretic Engine for SATCOM. A hardware add-on for SATCOM Ground Control providing Electronic Defense (ED) in hostile RF environments. EDGES performs per-hop in-service signal-to-noise (SNR) based RF situational awareness using dynamic game theory-based DRA algorithms. EDGES has been developed for the wideband global satellite system (WGS) and protected tactical waveforms (PTW). At present, the IFT’s game theoretic DRA (IGDRA) engine is a software package that has been tested on an in-house developed SATCOM testbed. The IGDRA engine was running on a Raspberry Pi and sent DRA decisions via an Ethernet cable. Simulation results showed that IG DRA produces desired DRA decisions for per-hop SNR distribution cases in partial band partial time (PBPT) jamming scenarios.

IFT has feasibility results that have laid a solid foundation for the extension of the IDGRA software module to an FPGA-based hardware module, as well as enhance the RF situational awareness based on the autonomous assessment of per-hop, in-service, SNR ratio estimation. Future goals include: i) Autonomous impact assessment of per-hop, in-service, signal-to-noise ratio estimation, and radio interferences; ii) The engineering development of smart SATCOM hub controller to reduce interference encounter rates; and iii) Testing the real-time performance of eliminating or neutralizing the unfriendly radio and multi-access interference actions.

The envisioned the IGDRA hardware will be able to make timely and smart DRA decisions based on enhanced RF situational awareness. The final deliverable (FPGA-based IGDRA) is envisioned as a complete hardware add-on for any SATCOM ground control, for electronic defense in hostile RF environments. For technology licensing, there is potential for sales of various system innovations.

EDGES is envisioned as a complete hardware add-on for any SATCOM ground control, for ED in hostile RF environments. However, for technology marketing and licensing, there is potential for sales of various system innovations including, the IGDRA software, the per-hop SNR link estimator, and the USRP emulation testbed. Our product will support applications that include the WGS program, and the development of PTW terminals for AJ capability, efficiency, reliability and availability. IFT also has the intellectual property to realize the commercialization stage and attain a competitive advantage. IFT has 3 patents related to EDGES.

    One of my biggest sources of inspiration is nature. There are many amazing inspiring, complex systems and feats of engineering, from non-living (e.g. tectonic plate movement) and living, large (e.g. sperm whale) and small (e.g. archaebacteria in Yellowstone National Park), I never fail to find parallels to my own professional work. We truly have an awesome plant.
    As an avid reader another huge source of inspiration in stories, most notably science fiction. The exposure to other people’s imagination, in all genres pushes me to think more creatively and make connections is seemingly unconnected domains.
    If I had to sum up what inspires me in one, it would be diversity. Diversity in exposure, diversity in schooling, diversity in socialization. The more I learn and experience world from different perspectives, the more fodder I have for new ideas. NASA Tech Briefs are a go-to source for technology diversity. The wide range of easy to digest summaries of new products and publications allow me to define problems more completely, inspire the what if, and expose me to products and tools I can leverage in creating the future.
