A WIDE APERTURE, HIGH DIRECTIVITY, SCANNED ANTENNA ARRAY

Abstract

The design is presented of instrumentation developed to record the complex amplitude distribution of pulsed radio waves after reflection by the ionosphere. The method of recording has as its basis a semiconductor switch which provides rapid scanning of 6 antennas placed in a linear array. Although observations are currently being made visually with film recording, provisions were made for changeover to a digital recording method for analysis by a high speed computer. Complete descriptions of the various parts of the equipment are given, and preliminary results obtained by the visual method are shown.
