ANTENNA SYSTEMS WITH CIRCULAR TRANSMIT ARRAY: POTENTIALITIES
Abstract
In order to provide efficient spatial summation of radiated power
and reduce the transversal dimensions of continuous-wave
radar antenna system a concept of transmitting antenna shaped
as a circular array is proposed. It is designed as a ring of radiators
placed around a single aperture of receiving antenna. The problem
of optimal size selection for such an antenna system
in terms of maximum gain and geometrical dimensions minimization
is solved. The antenna radiation pattern is analyzed, and
the side lobes level estimated.
