Emulate the responses of real-world targets in any scenario
Sigma Defense’s Multi-Functional Radar Simulator (MFRS) is a fully composable, closed-loop real-time threat radar simulator. MFRS is engineered to support the evolving needs of EW development, operational testing and operator training with unparalleled flexibility and precision.
Through systems like MFRS, Sigma Defense ensures that developers and warfighters have the most realistic possible training and test environments short of a real conflict.
Features
- User-Programmable Architecture. MFRS features a highly configurable software-defined architecture. Operators can easily program it to replicate a wide variety of radar threat signatures and behaviors. This flexibility allows training and test personnel to switch between different threat systems or create new ones on the fly, future-proofing the system as new threat intel emerges.
- High-Fidelity Signal Generation. MFRS produces radar signals that accurately emulate the nuances of real radar hardware—from waveform modulation and pulse repetition to antenna scan patterns. This high fidelity ensures the receiving systems cannot tell the simulator from a real threat, which is crucial for valid testing and training. By adjusting parameters, we can simulate everything— from older analog radars to modern digital phased array systems.
- Closed-Loop Realism. Our simulator operates in a closed-loop configuration, meaning it can interact with systems under test in real time. For example, when an EW system emits a jamming signal, the MFRS threat radar will react just as a real adversary radar would. This closed-loop capability provides authentic engagements and dynamic responses, so EW operators and equipment experience the full cycle of detect-track-engage-counter engage.
- Lab and Field Integration. MFRS is compact, modular, and designed with both lab and range use in mind. In a lab setting, it integrates into existing test benches or anechoic chambers, supporting rapid development cycles and iterative testing for EW engineers. For range operations, it can be deployed forward to support open-air exercises. In both cases, the simulator’s open architecture allows easy integration with other equipment and control software, fitting seamlessly into the user’s workflow.
