THE ANTENNA NETWORK FOR MONOPULSE DIRECTION FINDING REALISED ON THE BASE OF THE BUTLER MATRIX

摘要

The paper presents the conception of the antenna network for monopulse direction finding of a signal received from emission source. In the antenna network Butler matrix was used. Butler matrix connecting with circular array makes possibility monopulse direction finding in a azimuth plane of received signal on the base of measured phase between definite output ports. In presented structure direction finding of emission source takes place by means of monoimpulse-phase method, which in proportion to monoimpulse-amplitude method makes possibility to obtain higher accuracy of a determination of received signal direction. In this paper we include theoretical analysis and experimental results realised antenna network. Good agreement between results of the experiment and the theory was obtained.
