Abstract

The design procedure of noise temperature of antenna - non-uniformly heated radome system, taking into account multiple reflections inside a radome wall is offered. The results of noise temperature calculations for each of partial directivity diagram of the multibeam antenna and influence of radiometric images distortions brought at it on position finding reliability of radiometric navigation systems are presented.
