ABSTRACT:
A conformal array antenna system is disclosed comprising a structural base body having a shape suitable for a surface of an airplane or a ship, and a plurality of antenna units disposed on the structural base body. Signals received by these antenna units are converted into digital signals and fed to a digital beam forming circuit which synthesizes such digital signals to form a multiplicity of beams. The antenna units and the digital beam forming circuits may be connected by electrical transmission lines or optical fibers.
