Popis:	An interesting variation of the classical problems involved in synthesizing desired sonar transducer beam patterns is to examine the effects caused by missing acoustic radiating elements. Beam patterns were calculated for a multi‐element circular array using discrete frequencies and a composite beam pattern was calculated for a decade bandwidth. The same beam patterns were then calculated omitting single elements and groups of elements for analog and polarity sampling beam forming networks. The results are discussed in terms of rotating and fixed beam sonar systems.
