Radar Threat Simulators

Sigma Defense specializes in the design, development and production of high-fidelity threat simulators, advanced electronic warfare training systems, and comprehensive radar upgrade solutions. Our goal is to support the mission readiness of military and intelligence operators worldwide through realistic training and testing.

Simulator Solutions and Capabilities

Air Defense and Strategic Radar Simulators. We engineer and deliver realistic RF jammers and custom sensor systems that emulate the ever-evolving threat landscape. These systems replicate enemy radars and weapons sensors with unmatched realism, meeting rigorous operational requirements for test and evaluation, training, and mission rehearsal.
On-Demand Realistic Scenarios. Operators can use our simulators to engage with true-to-life EW scenarios on demand. This capability allows warfighters to practice detecting and countering threats in a virtual environment, improving mission proficiency and system familiarity without the expense or risk of live exercises. Crews can “train as they fight,” reacting to threat emitters and jamming signals that behave just like the real thing.
Live-Virtual-Constructive (LVC) Integration: Sigma Defense systems support LVC training across standard protocols (Distributed Interactive Simulation [DIS] and High-Level Architecture [HLA]). We maintain rich libraries of threat profiles that can digitally simulate tactical systems in real time. This means our simulators can be injected into live-fly exercises or linked with virtual training devices, creating a blended training environment where all participants see a consistent, realistic threat picture.
- With training solutions for the U.S. Navy’s surface and subsurface EW community such as the Battle Force Electronic Warfare Trainer (BEWT) AN/USQ-T47 (V) [link to product page], sailors can train for tactical operations using the actual tactical equipment.
- BEWT also enables the onboard training team to exercise individual, team, combat systems team, and force level operational scenarios.
Turnkey Solutions & Lifecycle Support. Sigma Defense specializes in designing, developing, integrating, testing, and sustaining threat simulator and sensor systems throughout their life cycle. From initial concept and cradle-to-grave development, to fielding the system on site, training the operators, and providing ongoing upgrades and technical support — Sigma Defense offers a full turnkey solution. We ensure that as threats evolve, your training systems also evolve through incremental upgrades and enhancements.

Radar and EW Training Systems Expertise

Open-Air Radar (OAR) Simulators. These include full-function radar threat simulators that are deployable on open-air test ranges—replicating enemy search, acquisition, and engagement radars for live aircraft training.
Laboratory HWIL Simulators. We develop closed-loop, Hardware-in-the-Loop systems for the lab, where real seeker or radar hardware can be fed a synthetic but high-fidelity RF environment. These lab systems inject realistic signals and electronic countermeasures (ECM) into radar or missile receivers, enabling developers to test against true threat reactions without leaving the lab.
Environment Generation Subsystems: These include high-performance signal generation components that create a realistic RF environment (dense signal scenarios, multiple overlapping threats, background clutter, etc.) and inject it into radar, EW receiver, or missile seeker hardware. This provides stress testing of sensors and jammers under combat-like signal conditions.

Early Warning & Acquisition Radars. We develop simulators for early warning networks and acquisition radars that opponent forces use. This enables comprehensive training for every stage, from initial detection through engagement.
Complete Lifecycle Support. Sigma Defense provides cradle-to-grave development and support, including on-site installation, activating the system at the customer’s location, and follow-on sustainment. We remain a long-term partner, ensuring systems continue to operate at peak performance and incorporating new threat modes as needed.
