RADIOHOLOGRAPHIC METHOD FOR DETERMINING DIRECTIVITY PATTERN IN ANTENNA FREQUENCY RANGE Russian patent published in 1997 - IPC

Abstract RU 2089921 C1

FIELD: radioholography; measurement of antenna and radiating equipment parameters. SUBSTANCE: method involves excitation of analyzed antenna by pulse signal and radiation of pulsed electromagnetic field by this antenna, recording of this field by various types of transducers, measurement of directivity pattern of analyzed antenna at desired frequencies by means of Fourier transformers with respect time and spatial variables according to which, prior to starting Fourier transforms, bearings should taken coordinates of elementary sources and intensity of these sources measured; field recording is made by several fixed transducers. EFFECT: facilitated procedure; enlarged functional capabilities. 1 dwg
