The OUSD(R&E) Prototype & Experiments DoD RPF SASSY project is to develop a Radio Frequency (RF) sensor prototype to generate spectral situational awareness (SSA), dynamic spectrum access (DSA), signal identification (Signal ID), direction finding (DF), and various decision level processing (i.e. Metacognition) to provide and maintain radar capabilities in congested and contested electromagnetic environments (EME).

To address these project goals, we created a technical eco-system of government laboratories, academia partners and contractual vendors.  This technical eco-system collaborated in the development of a Sensor Open Systems Architecture (SOSA) 3U Open VPX Chassis (>=3 slots) that houses the RF System on Chip (RFSoC) software defined radio (SDR) platform, single board computer (SBC) providing command and control (C2) and external system interface, and a hardware accelerator (Graphics Processing Unit) for advanced processing. 

The SASSY software architecture (Open/CL) is fully government-owned IP that can be leveraged by the DoD community to address a variety of RF and radar applications related to spectrum dominance.  Specific to this demonstration we will show the functionality of the following:

  • Wideband (WB) Fast Spectral Sensing (FSS) on a 2.5GHz instantaneous bandwidth input channel
  • Demonstrate Narrowband (NB) FSS and Signal ID algorithms for all occupied sub-bands within a 100 MHz channel tuned within the WB channel, demonstrate NB DSA, based on the active sense and react to avoid algorithm
  • Metacognition decision process for DSA with pulsed chirp radar waveforms with adjustable bandwidth to exploit the largest unoccupied sub-band in a NB channel and demonstrate Direction Finding (DF)
  • We will also show supplemental research that complements the end prototype development.
