Ad-Hoc Ground Based Counter-Fire System Navy SBIR FY2014.2 Sol No.: Navy SBIR FY2014.2 Topic No.: N142-086 Topic Title: Ad-Hoc Ground Based Counter-Fire System Proposal No.: N142-086-0720 Firm: Hyperion Technology Group, Inc. 3248 West Jackson Tupelo, Mississippi 38801-4026 Contact: William Frazier Phone: (662) 823-0600 Web Site: http://www.hyperiontg.com Abstract: Acoustic sensors, such as the Ground Counter Fire Sensor (GCFS), are used by the USMC to identify the point-of-origin (POO) and point-of-impact (POI), as well as provide source identification. This effort will develop a proof-of-feasibility set of signal processing algorithms for the GCFS's Command Post (CP). These algorithms will permit a network consisting of a mixture of up to 12 fixed listening posts (LPs) and relocatable LPs (RLPs). The CP will de-conflict simultaneous events and identify POO / POI as well as the firing platform with the accuracy stated in the solicitation as an optimal goal. Hyperion will develop a robust event location estimation algorithm. A stochastic data fusion method will be developed for handling simultaneous events. Acoustic ray-tracing and wave propagation estimators, using meteorology and terrain data, will be used to achieve highly accurate calculations of event time and location and support improved event type identification. As a benefit of this work, the USMC can implement an improved sensor network, lessening the logistical burden on the Warfighter in regards to emplacement, operation and maintenance. Benefits: Derivative applications include the improvement of a number of acoustic processing systems. For example, on a different range scale (100's and 1000's of km) geo-location and event identification methods are utilized by the International Monitoring System (IMS) Infrasound Network which supports the Comprehensive Test Ban Treaty Organization (CTBTO). For Homeland Security, these technologies could play a key role in detecting, geo-locating (3-D) and tracking low-flying unmanned aerial vehicles trying to cross-borders or enter a restricted airspace.
