The call under EDF-2025-DA focuses on a highly strategic development action aimed at demonstrating the integration of state-of-the-art radar technologies for advanced naval and air surveillance applications. This funding opportunity is specifically targeted to address the growing challenges in the maritime domain, where increasingly contested operational environments demand innovative sensor capabilities. With a particular emphasis on enhancing interoperability and improving overall situational awareness, the call seeks proposals for a multiband 4D radar demonstrator that can operate seamlessly in complex, congested electromagnetic spectrums. Over the past decade, rapid technological advancements in RF electronics, digital technologies, photonics, and smart antennas have paved the way for the next generation of radar systems. These systems are envisioned to go beyond traditional multiple-radar sensor approaches by adopting a multifunction radar netted strategy that leverages integrated machine learning, multiplatform virtualisation, and cloud/edge computing. In this context, the multiband 4D radar demonstrator is expected to deliver simultaneous operational capabilities across sea, land, air and even space, thus providing a robust response to modern electronic warfare challenges such as jamming and interference.

The call is structured to fund a single project initially, although the possibility exists to support additional proposals based on quality and budgetary availability. The demonstrator is expected to cover a range of technical areas including intelligent electromagnetic spectrum management, integration of bidirectional communications for weapon datalinks, and full compatibility with advanced combat management systems. A key part of the project is the development of a scalable Active Electronically Scanned Array (AESA) design that is both modular and adaptable, allowing it to be integrated into various naval platforms as well as potentially extending its application to ground and air surveillance systems in the future.

Proposals must outline a clear roadmap that identifies technology needs and addresses the risk mitigation for product feasibility. They are required to include detailed simulation studies, a comprehensive software model (or digital twin) of the demonstrator, and performance testing in both controlled and realistic operational environments. The integration of advanced algorithms for spectrum management and target detection under adverse conditions forms a central pillar of the proposed approach. In addition, the project is expected to explore the incorporation of multifunction capabilities that merge radar and communication functions, thereby enhancing cooperative engagement between remote assets and the central command infrastructure.

Furthermore, the call emphasizes the importance of interoperability and scalability, ensuring that the final system can be readily integrated with existing and future EU defence systems. This alignment with broader strategic objectives is expected to enhance the technological superiority and strategic autonomy of EU Member States and associated countries. The demonstrator will serve as a proof-of-concept, validating its potential to meet critical performance indicators in terms of detection accuracy, resilience to electronic countermeasures, and overall system efficiency.
