RF Test & Simulation Systems

  • RF Environment/Channel Emulator

  • Modeling & Simulation (M&S) and Hardware-in-the-loop (HiTL), Testing & Evaluation (T&E)

  • RF Digital Twin performance testing

  • RF Virtual Reality creation. Dynamically emulates realistic RF environments, including congested and contested conditions

  • High-Fidelity, repeatable RF systems testing in the lab with real-world field quality characteristics

  • Development and testing asset optimized for modern RF technology like SDRs

  • Scalable to support user capacity needs, small to massive RF scenarios

  • Supports accelerated RF development and time-to-field

  • Supports Virtual Nodes (VSUs: virtual models of systems) and/or Physical Nodes (PSUs: Real systems that can be connected to DYSE for test and simulation purposes)

  • Testbed for 5G, Spectrum sharing, Resilient PNT, Cognitive Radio, Tactical and LPI/LPD communications systems, EW systems, and more

How It Works

  • RF devices under test interconnect through synthetically generated RF  environments

  • RF paths between devices emulate the impact of real-world  RF operational conditions - paths are individually programmable

  • Physical devices can interact with virtual devices - full-mesh interconnection

  • Device interactions take place through the DYSE Virtual RF Environment (VRE) at digital baseband 

  • Hardware-in-the-Loop (HiTL) interfaces provide analog RF connections for  physical devices

Modeling and Simulation With DYSE

DYSE can be used to develop and refine RF designs, concepts, applications, and algorithms. When performing Modeling and Simulation, DYSE passes data produced by RF device models through mathematical and statistical channel models to predict performance under user-selected  RF operating environments.

DYSE emulates operationally realistic operating environments so users can validate concepts, refine capabilities, and assess performance through Modeling & Simulation before proceeding to  physical device Test & Evaluation and/or field testing.

Users can create test scenarios consisting of physical and virtual nodes. Any and all nodes can be “placed” on terrestrial, airborne, or space platforms with associated antenna patterns and 6 DOF motion. DYSE models the RF propagation paths between nodes, introducing a wide range of operationally correct propagation effects.
