Suppression of mutual influence of antenna channels, which accomplish self-pointing guided by information signal through geometric ratios optimization of irradiators construction

Abstract

For realization of self-pointing with the help of mirror antennas of ground stations by an information signal it is necessary to have 4 irradiators minimum. All irradiators, as it is known, should be placed on a small distance from focal axis of a mirror for displacement of partial radiation patterns, which are forming direction-finding characteristic with the help total-differential systems. Therefore irradiators are in a zone of significant mutual influence, which can complicate both bearing and accuracy of self-pointing. Really, at exact pointing of the radiation patterns of the antenna on the flying device on one angular coordinate the interfering signal because of mutual influence of pair irradiators, which define other angular coordinates, can appear and this will result ion a failure of auto-support on first angular coordinate. Therefore, the development of ways of lessening mutual influence of antenna channels, which realize self-pointing by an information signal, is urgent. Usually, the mutual influence is estimated either as a factor of connection, or mutual resistance, concerned to it [VN Rudenko et al., 1972]. In the given work we shall consider a dependence of factor of connection (mutual resistance) from geometrical parameters and from mark of polarization of regular spiral antennas, and also from their mutual orientation.
