Paper Abstract

The opportunities and features of applying multi-focused antennae based on Fresnel lens to the problems of acoustical brightness thermometry have been studied. The technical feasibility of the device equipped with these antennae has been analyzed. The method has been suggested for the optimization of choosing radii of Fresnel lens rings providing acceptable focusing quality at various distances taking into account the peculiarities of acoustical brightness thermometry -- wide-band signal receiving in millimeter range and frequency-dependent acoustical absorption.
