Radio Frequency Generation (RFGEN) Subsystem Development and Integration (SDI) Prototype Project

The Naval Air Warfare Systems Command (NAVAIR) desires to further advance its capabilities in the areas of electronic threat simulation and measurement focusing specifically on advances in the areas of system concept, architecture development, and requirements definition. The overall goal is to meet the increasingly critical requirements for current and future Department of Defense (DOD) aircraft, which contain electronic combat support systems. To meet this goal, NAVAIR is developing a new simulator program called NEWEG, which consists of a single configurable set of unclassified subsystems. The set contains one Scenario Simulation and Control (SSC) subsystem, one or more DGEN subsystems, one or more Radio Frequency Generation (RFGEN) subsystems, and a Measurement and Analysis subsystem. NEWEG is currently being developed in two Blocks: A and B. The RDGEN system will be developed, demonstrated and assessed as part of Block B. The unclassified RFGEN prototype project will focus on the continued development and testing of the RFGEN subsystem.

The objective of the RFGEN prototype project is to design, develop, fabricate, assemble, integrate, and test the NEWEG RFGEN subsystem as part of a new simulate development program at the US Navy Air Station (NAS) Patuxent River, MD. Specifically, the RFGEN prototype project will develop and integrate NEWEG capabilities that will generate the RF signal with the proper emitter modulations in frequency, amplitude, time, Doppler, and phase, as directed by the Pulse Descriptor Words (PDW) from the DGEN subsystem. . The RFGEN prototype will also transmit these signals either free-space radiation or by direct-injection using RF-over-fiber devices or RF cabling to the SUT. For direct inject mode, the RFGEN prototype will translate the time of arrival, amplitude, phase, and Doppler frequency from the System Under Test (SUT) to each individual port. Additionally, the RFGEN prototype will perform pulse arbitration based on available resources and real-time calibration. Finally, the RFGEN prototype will apply calibrations to the RF command word.
