Abstract

PURPOSE: To suppress the side pole to the extent permissible from the practical standpoint, by setting the rate of synthesis and the ring arrangement radius to optimized value, in synthesizing a plurality sets of the vibrator groups arranged in concentricity.
CONSTITUTION: The wave transceivers Z0 are arranged for the oscillators in ring shape in radius D/2, and the transceivers Z1 are arranged in D1/2 radius and the transceivers Z2 are arranged in D2/2 radius. Further, the diameters of the ring shape vibrators D1, D2 are set as D1=0.6D and D2=1.5D and the characteristic curve of the transceivers Z0, that of Z1 and that of Z2 are synthesized in the rate of respectively 1, 0.9 and 0.9, to minimize the side pole at the synthesized directivity.
