Mitigation of Military Communication and Radar System Interference from Current and Future Fixed and Mobile Wireless Broadband Systems

This Phase I proposal for unclassified basic research and exploratory development titled Mitigation of Military Communication and Radar System Interference from Current and Future Fixed and Mobile Wireless Broadband Systems: Interference Resilient Waveforms is submitted in response to Department of Defense SBIR Program Solicitation Number 14.2, Topic N142-106. This proposal outlines an innovative cooperative research and development effort headed by ANDRO Computational Solutions, LLC with commercial communication systems consultant Dr. Liu, and advanced radar and JSF advisor from Lockheed Martin Dr. Kryzak. The team will develop a solution enabling air-to-air missions at low altitudes in the environment with in-band interference from Unlicensed National Information Infrastructure (UNII). We will propose waveforms effective in heavily occupied relevant RF spectrum, inundated with dynamic composite signals of various encoding and modulations. In addition to waveform designs, for a multi-tiered interference mitigation, our concept considers deception and signal exploitation techniques, aimed to invoke favorable UNII response and fortuitous RF illumination/shadowing respectively. The team will develop waveform designs suitable for use in Navy airborne radar systems operating in the presence of UNII devices and an implementation plan showing how the techniques can be integrated into the radar system and extended for use in airborne data link systems.
