Radar Design and Development

Sigma Defense provides comprehensive radar system design and development services that extend beyond simulators. We have in-house engineering teams covering analog and digital hardware, embedded software and full system integration. This enables us to deliver scalable, mission-ready radar systems for sea, air, land or test range applications.

Features and Capabilities

Large-Scale Radar System Design. From initial architecture through final integration, our engineers design full radar systems tailored to specific mission requirements. We handle system modeling, antenna and RF front-end design, signal processing algorithms, and software/hardware integration. The result is a turnkey radar solution optimized for our customer’s concept of operations.
Open Architecture & COTS Approach. We prioritize modular, open-architecture designs and leverage commercial off-the-shelf (COTS) components whenever possible. This ensures affordability and interoperability and supports future technology insertions. Customers benefit from reduced costs and easier upgrades, as our radars can evolve with minimal redesign.
Embedded Real-Time Software. Our software team specializes in low-latency, real-time processing code for radar operation. Whether it’s firmware for Field-Programmable Gate Arrays (FPGAs) or algorithms running on DSPs, we develop software that meets the high-speed requirements of modern radars. This means our systems can detect and track targets in cluttered, fast-changing environments without missing a beat.
High-Performance Hardware Design. We design custom high-performance hardware such as FPGAs and digital signal processor boards for specialized radar functions. These enable fast waveform generation, agile frequency hopping, and real-time adaptive processing. Additionally, agile reconfiguration is built in. For instance, our hardware can switch modes or waveforms on the fly to respond to new mission demands.

Advanced Signal Processing (ASP): We employ advanced digital signal processing techniques for target detection, tracking and identification. From pulse-Doppler processing to machine learning-based target classification, our radar systems extract maximum information from returns. The result is precise simulation and target characterization in test scenarios and superior performance in real operations.
Threat Environment Simulation: Sigma Defense combines radar development with threat simulation expertise to ensure your systems are evaluated against the real threats they’ll face. Leveraging our deep knowledge of current and emerging radar threats, we incorporate validated threat models into radar system development. For military customers developing EW systems, we can provide simulation environments and threat injects to test those systems.
Cross-Platform Integration: Whether the radar is deployed on a naval ship, an airborne platform, a ground vehicle, or a fixed test range—we design for smooth integration. Our radars meet size, weight and power constraints of various platforms and conform to standard interfaces. This cross-domain experience ensures that when a Sigma Defense radar is fielded, it plugs into the existing ecosystem of that platform seamlessly—from power and cooling to command/control interfaces.

By offering radar design as a service, Sigma Defense enables customers to field custom sensors finely tuned to their mission—without the overhead of maintaining a large in-house development team. We deliver end to end, from design to prototype to production and sustainment.
