A technique for obtaining a significant increase, compared to more conventional means, in percentage bandwidth for a projecting transducer has been developed. Multiple sets of elements with each set tuned to a slightly different frequency are used to obtain the increase in bandwidth. Phase problems at midfrequencies normally associated with multifrequency operation are solved to a satisfactory degree. An analytical study concerned with bandwidth, beam pattern, and relative per‐element sensitivity is presented. Experimental data are shown to support the analytical study.
