Multi-Algorithm Unique Emitter Identification
This SBIR develops innovative SEF algorithms, overall methodology and techniques to fuse multiple algorithms to provide unique emitter identification in an open architecture real-time context for a submarine EW/ISR system. New as well as existing techniques for conventional, very narrow and wide pulses and intentionally modulated emitters (including FMCW) are investigated and characterized. This effort leverages RAS"Multi-Technique SEI Test-bed (FPGAs, and C/C++ code) to demonstrate multiple simultaneous algorithms provide increased identification performance and high confidence accurate reports. The effort builds on existing RAS multi-technique algorithms for emitters employing solid state, phased array, and advanced modulations. Techniques include intra-pulse features on instantaneous frequency, phase and intentional modulations, and multiple pulse temporal and spectral features. Hardware and software approaches are assessed and three or more algorithms in a well defined, open computational architecture were selected for PHASE II COTS NDI hardware implementation and demonstration with a 1 GHz IF. Interface control software allowing intuitive operation of the system and automatic techniques will minimize operator interaction and provide high confidence emitter reports. After Phase II, RAS will work with platform primes and the government to install and provide a technology demonstration on the BLQ-10(V) upgrade platform.
