This report describes the work performed on a study of a reflector antenna that provides zoom variable beamwidth and scan capability using controlled aperture amplitude and phase. The antenna consists of a primary reflector paraboloid and a secondary reflectorlens. It operates as a lens in conjunction with one feed for scanning in the receive mode and as a reflector in conjunction with another feed for zooming in the transmit mode. Switching between a zooming transmit mode and a scanning receive mode results in a versatile radar antenna with an inherent duplexing capability. The performance of this antenna system is being analyzed numerically with the aid of digital computers. This report describes the physical principles used to analyze specific geometric configurations and some of the computer programs. Author
