Train as You Fight with Rapid & Realistic Threat Scenarios
Sigma Defense specializes in designing, developing and producing high-fidelity threat simulators, 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.
We remain a long-term partner by providing complete lifecycle support—ensuring our solutions consistently operate at peak performance and incorporating new threat modes as needed.
Open-Air Radar (OAR) Simulators
These include full-function radar threat simulators that can deploy on open-air test ranges—replicating enemy search, acquisition and engagement radars for live aircraft training.
Environment Generation Subsystems
These include high-performance signal generation components that create a realistic RF environment and inject it into radar, EW receiver or missile seeker hardware. This stress tests sensors and jammers under combat-like signal conditions.
Air Defense and Strategic Radar Simulators
We engineer and deliver realistic RF jammers and custom sensor systems that emulate the evolving threat landscape. These replicate enemy radars and weapons sensors with unmatched realism—meeting rigorous operational requirements for test and evaluation, training, and mission rehearsal.
Live-Virtual-Constructive (LVC) Integration
Our systems support LVC training across standard protocols. 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 trainees see a consistent, realistic threat picture.
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.
Laboratory HWIL Simulators
We develop closed-loop, Hardware-in-the-Loop systems for the lab, where real seeker or radar hardware is fed a synthetic but high-fidelity RF environment. These lab systems inject realistic signals and electronic countermeasures into radar or missile receivers, enabling developers to test against true threat reactions without leaving the lab.
On-Demand Realistic Scenarios
Operators can use our simulators to engage with true-to-life EW scenarios on demand. This lets warfighters 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.
Turnkey Solutions & 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 ensure that as threats evolve, your training systems also evolve through incremental upgrades and enhancements.
