Modular design principles for missile defence early warning radar

This paper focuses on the innovative architecture of the ground-based UHF Deployable Early Warning (DEW) radar. First, the early warning functions of the radar with the main requirements are presented. Then the surveillance principles and the global radar functional architecture are depicted. The central part of the paper shows how the mission requirements can be met through an innovative modular and digital antenna architecture based on software radar technology, Building Blocks and standard interfaces concepts. The Building Block design principles are described. This approach is demonstrated through examples emphasising the modular design flexibility. Furthermore, the proposed Building Block can be used for creation of other UHF radar products.
