Software-Defined Radar Development for Naval Systems

Raytheon, an RTX business, has received a contract from the U.S. Office of Naval Research to further develop software-defined radar capabilities for next-generation naval radar systems. The cooperation focuses on modular radar software architecture designed to improve operational flexibility, spectrum management, and multi-mission functionality in maritime defense applications.

Industrial and Operational Context
Modern naval platforms increasingly operate in congested electromagnetic environments where military and commercial systems compete for spectrum access. Radar systems must therefore support adaptive frequency management while maintaining surveillance, tracking, and defense capabilities. The cooperation between Raytheon and the Office of Naval Research addresses these challenges through software-defined radar technology and digital infrastructure approaches that allow radar modules to operate with greater autonomy and coordination.

The project targets naval defense applications requiring simultaneous mission execution, including surveillance, target tracking, and communication support within contested spectrum environments. Improved spectrum sharing with commercial 5G networks is also part of the development objective.

Technical Architecture and Partner Responsibilities
Under the contract, Raytheon’s Advanced Technology team is responsible for developing the radar software framework and validating system functionality through demonstration activities. The Office of Naval Research supports the program as the contracting and research authority overseeing technology development for future naval deployment.

The software architecture is based on software-defined apertures in which individual radar building blocks operate independently rather than as a fixed monolithic system. Each module functions as a programmable aperture capable of dynamically adjusting operational parameters according to mission requirements and spectrum conditions.

This modular approach enables the radar system to allocate resources across multiple simultaneous tasks while reducing the need for hardware redesign during future capability upgrades. Software-based modifications can be implemented incrementally, supporting faster adaptation cycles and lower integration risk compared with conventional radar modernization methods.

Deployment and Validation Activities
Following software development, Raytheon plans to conduct demonstration programs to validate independent module control, multi-mission operation, and spectrum-sharing capabilities. These demonstrations are intended to verify system behavior under operationally representative conditions before transition into naval radar platforms.

The development program also includes integration testing related to frequency coexistence with commercial wireless networks such as 5G infrastructure. This is intended to support improved electromagnetic spectrum utilization in maritime operational environments where civilian and defense systems increasingly operate in overlapping frequency bands.

Expected Technical Impact
The cooperation is intended to improve radar adaptability, scalability, and maintainability through software-centric engineering. By separating capability enhancement from hardware redesign cycles, naval operators may be able to introduce operational updates with reduced system downtime and lower lifecycle engineering complexity.

Colin Whelan, president of Advanced Technology at Raytheon, said: “With precise, software-driven control over where and how we radiate, we're taking an important step forward in how we use software-defined apertures to keep pace with evolving mission demands.”
