In the acoustic equipment of Sonar Systems used in transponders or moving bodies, a projector is mounted on one end of a cylindrical tube. From this configuration, the reflective wave from the tube end is induced, and the directivity pattem of the projector is degenerated. This effect can be minimized by formulating a correctly shaped reflecter (;baffle) and inserting it between the projector and the tube.However, since there are few methods for calculating the acoustic field of such projector, how to design the reflecter shape to obtain a desireble directivity pattern is not completely clear. Hence, in this paper, we suggest an useful method for calculating the acoustic field so that we can provide a means of determining the best shape for the conical reflecter.
