Digital Early Warning Receiver (EWR) for the Next Generation Submarine Electronic Warfare (EW)

Sonalysts proposes to develop a prototype Digital Early Warning Receiver (DEWR) that fits within the digital architecture of the Next Generation Architecture (NGA) Submarine Electronic Warfare Suite based on the novel concept created during the SBIR N161-025 Phase I Base effort. The DEWR will employ a modular video detection and digitization layer with narrow acceptance bandwidths across the entire electromagnetic spectrum and high-speed analog-to-digital conversion. Under the Phase II effort, Sonalysts will generate a channelized prototype with representative form, fit and function, and conduct performance testing and demonstrations in an integrated electronic warfare environment. Digital signal processing algorithms are developed in embedded software to perform legacy EWR functions on digital data streams and publish results to downstream consumers.
