Air Vehicle Communication in a Denied Environment Navy SBIR FY2014.2 Sol No.: Navy SBIR FY2014.2 Topic No.: N142-095 Topic Title: Air Vehicle Communication in a Denied Environment Proposal No.: N142-095-0265 Firm: Coherent Technical Services, Inc. 46561 Expedition Drive Suite 100 Lexington Park, Maryland 20653 Contact: Ian Gallimore Phone: (301) 880-3341 Web Site: www.goctsi.com Abstract: The proposed research will lead to a hybrid laser communications and ultra wide band (UWB) radio frequency communication system that will provide the maximum throughput achievable (>>1Gb/s) with novel emerging state-of-the-art technology, while also providing graceful degradtion should laser communications be affected by atmospheric effects. The all-aspect UWB element provides the means to cue the directive laser communications element, while also providing high bandwidth fail-over capability. The UWB element can also be used by itself in electronic warfare environments. Novel means of digital notching and amplifier pre- and post-compensation schemes will provide anti-jam capabilities not now available, while simultaneously preserving more low probability of detection performance in comparison to other techniques. Benefits: The integration of laser communications with ultra wide band (UWB) radio frequency communications will produce high throughput communication links (>> 1Gb/s) that cannot be jammed, and that gracefully degrade to lower levels of performance in the presence of excessive atmospheric anomalies. When only UWB is available, digital notching and amplifier compensation provide the means to preserve communication links in contested Anti-Access Area Denial (A2AD) environments characterized by electronic warfare regardless of source. These technologies could open up greater spectrum for commercial use by maturing technologies at unused frequencies, while also allowing greater density for users of adjacent frequencies. As a result, these technologies could ultimately benefit every communication device in use today. Return
