Reference Template Generation for Cross-Correlation Based Receivers Navy SBIR FY2008.1 Sol No.: Navy SBIR FY2008.1 Topic No.: N08-068 Topic Title: Reference Template Generation for Cross-Correlation Based Receivers Proposal No.: N081-068-0294 Firm: Welkin Sciences, LLC 102 S. Tejon Suite 200 Colorado Springs, Colorado 80903-2200 Contact: J. Reinking Phone: (719) 520-5115 Web Site: www.welkinsciences.com Abstract: Welkin Sciences proposes to develop the Template Identification Processing System (TIPS), a very-high-speed digital signal processor implemented on the company's DataFlowDSP(TM) hardware platform, an interconnected network of FPGAs and embedded general-purpose CPU blades. The TIPS works in tandem with a cryogenic RSFQ-based sub-system to form a complete signal identification and discovery capability. The RSFQ components digitize a wideband RF input signal and the room-temperature TIPS analyzes the digitized signal stream to generate signal signature templates for previously unknown signals. The proposed TIPS design is intended to serve three purposes: 1) a development platform for real-time template generation algorithms; 2) a fielded first-article template generating processing unit that can be built and delivered within the budget and schedule limitations of an SBIR Phase II program; and 3) a development platform for the algorithms that match (or correlate) the received signal with the list of signal signature templates (ideally such algorithms would migrate to the RFSQ sub-system). The proposed TIPS design employs a truly open architecture philosophy based on COTS hardware components in the industry standard ATCA form factor. Software development tools used for this project are entirely open source (Linux/GNU), and the firmware is developed using the familiar MATLAB platform, the same toolset used to develop and refine the DSP algorithms in the conceptual design phase prior to implementation. Benefits: A template identification processing system with a low noise digital receiver and high speed real-time signal processor will allow unidentified signals to be more accurately identified and searched for in subsequent signals. The technology will find application in DoD Intelligence, Surveillance, and Reconnaissance systems. Non-DoD applications of the proposed technology include spectrum monitoring by regulatory agencies as well as spectrum sensing by secondary users in smart radio systems. Return
