MICROWAVE POWER DISTRIBUTION SYSTEM FOR AN AIRBORNE RADAR SYSTEM

摘要

The invention relates to an antenna system (1) for an airborne radar system. The antenna system (1) comprises a number of first antenna elements (2) and a microwave power distribution system (3) comprising a number of first T/R-units (4) being coupled to the first antenna elements (2) for distribution of microwave power to the first antenna elements (2). The invention is characterized in that the microwave power distribution system (3) comprises an assembly of waveguides (6; 6a; 6b) coupled to a number of second antenna elements (7) directed at an angle essentially perpendicular to the number of first antenna elements (2), wherein the first T/R-units (4) are coupled to the waveguides (6; 6a) for distribution of microwave energy to the second antenna elements (7).
