REFLECTOR ANTENNA ZOOM TECHNIQUES

Abstract

The report describes the work performed during the second quarter of 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 reflector/lens. 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 development of a computer program for solving the Fraunhofer aperture integral efficiently and with good accuracy.
