T1 INVESTIGATION OF THE POSSIBILITY FOR DESCRIPTION OF THE SPATIAL FIELD DISTRIBUTION NEAR A MOBILE RADIO DIRECTION FINDER ANTENNA SYSTEM BY A LAURENT SERIES JF Telecommunications and Radio Engineering JO TRE YR 2012 FD 2012-05-16 VO 71 IS 9 SP 803 OP 816 K1 radio direction finder K1 ring antenna array K1 field approximation K1 amplitude-and-phase distribution AB A method for description of the spatial distribution of an electromagnetic field near a ring antenna array of a mobile radio direction finder, based on the hypothesis on possibility of application of theoretical tools of analytical functions of the complex variable z = x + iy, is presented. In particular, it is shown that application of the Laurent series allows generating a virtual antenna array, used for enhancing the resolution by the azimuth and the accuracy of radio source location in a broad frequency band.
