Abstract
A method for providing a broadband constant beam width acoustic array includes providing a transducer array in an axisymmetric configuration. A beam width is specified, and an integer order Legendre polynomial is determined for that beam width. A control parameter is determined that will increase the integer order Legendre polynomial to that beam width. The Legendre polynomial is used to provide a shading function for the array of transducers that will give the specified beam width.
