Dual frequency multi-function radar antenna research

In 1995 the MESAR (Multi-function Electronically Scanned Adaptive Radar) MFR research group at DRA Portsdown West began investigating dual frequency radar concepts under the Corporate Research Programme to overcome the current compromise in operational frequency choice. This work is discussed and builds upon the considerable expertise that has been gained with the highly successful MESAR MFR programme which began in 1977. The results of the research indicate that a dual-band MFR based upon the currently postulated design has the potential to overcome the existing single frequency compromise of MFR, leading to significant benefits for military weapons sensors. The continuing theoretical research, together with the planned practical demonstration of the concepts, will enhance understanding of dual-band arrays and increase confidence in the ideas detailed in this paper. In conclusion, all of the research points towards a potentially successful candidate to continue the UK´s pioneering research into ship-based weapon system multi-function radars
