The way of formation of direction finding characteristic with use a equidistant circular antenna array made of directional antennas


A.D. Vinogradov, P.A. Levashov, V.A. Mylnikov

The way of formation in an analytical kind peak direction finding characteristics a wideband radio direction finder with equidistant circular antenna arrays from the directional antennas characterized by cosine azimuthally dependence of the main petals of radiation pattern is considered. On a realization example wideband radio direction finder six-element and ten-element equidistant circular antenna arrays with log-periodic antennas of vertical polarization possibility of formation peak direction finding characteristic in circular azimuthally sector with a constant steepness and small methodical errors of direction finding in the conditions of aprioristic uncertainty of parameters of distortions of radiation pattern of antennas is shown.
