Enhanced De-Interleavers for Submarine Electronic Warfare Support (ES) Systems
This SBIR develops new innovative clustering and de-interleaving algorithms, leverages and refines existing algorithms and software, and integrates them within an open architecture framework to address a wide variety of radar signal classes for a submarine EW/ISR application. The proposed effort addresses several challenging emitter waveform classes for which current approaches are noted to have problems (per solicitation). This effort leverages RAS Multi-Algorithm Unique Emitter ID SBIR Phase I/II and end-to-end Directed ELINT Process (DEP) software modules (C/C++ and MATLAB) for clustering, RF Agile clustering, cluster correlation, track association, and emitter typing. It exploits previously developed Specific Emitter Features (SEF), not only for Specific Emitter ID (SEI), but also for cluster correlation, specific emitter tracking (SET) and RF agile processing. Approaches are assessed and selected for PHASE II software development and demonstration within the Processing Layer of the NAVSEA NexGen EW system architecture concept. Interface and control software, operating within an Ozone Widget Framework, enables automatic system operation to minimize operator interaction (with manual override and configuration control) provide high confidence emitter processing and reporting. After Phase II, RAS will work with platform primes and the government to install and demonstrate the technology on a suitable submarine platform testbed.
