Advances in affordable Digital Array Radar

This paper firstly reviews the issues and benefits of various levels on digitisation in a DAR (digital array radar) as discussed above. It then focuses on the key technology of high levels of digitisation; that of low cost, high performance, small and modular digital receivers. This paper presents current UK R&D employing low cost COTS components to enable this to be realised. Present S Band and X Band digital receiver designs are used as examples of state of the art modular hardware.
