ARROW SLATE LLC — Department of Defense SBIR Phase I: N221-073

Description

ArrowSlate seeks to design a modular and scalable standalone RF-Anomaly detecting receiver. The outcome of this proposal is to showcase real-time anomaly detection and alert within the order of seconds, and a goal on the order of microseconds. ArrowSlate’s solution is at minimum capable to detect RF anomalies for flexible, non-standard bandwidths under 500MHz, but can range from sub-MHz instantaneous bandwidth (IBW) to 5+GHz IBW. Our intent is to depict a proof of concept for a global RF anomaly detection that will fit many intended platforms including options for either software-only or hardware accelerated designs. This aids the adoption of this platform into various Navy program of record (PoR) receivers, and allows for adoption into any legacy receivers currently fielded. ArrowSlate asserts that the platform as proposed will not only perform the minimum required benchmarks as stated in the solicitation, but provide an immensely scalable base for future developments and system integration. This anomaly detection system is intended to serve the functionality of characterizing Radio Frequency (RF) emitter behaviors and patterns of life for a geographic area with no to minimal operator intervention. These RF behaviors include unexpected transmissions in time, frequency, or space (for any beamforming-capable nodes) domains. Additionally, our proposed system is designed to have the ability to detect anomalous modulation changes, radar pattern/pulse rate changes, anomalous Doppler shifts, and other "contextual anomalies".
