Abstract
The high frequency multi-mode pipe projector (HF MMPP) transducer has been employed in many applications since its inception. With its wide bandwidth, one of its uses has been as an acoustic source for underwater communications. The digital spread-spectrum with digital signal processing (DSP²) project identified the need for a more efficient underwater communications acoustic projector in the 35 kHz to 60 kHz band. Two versions of a new breathing-mode DSP² HF MMPP were developed using finite element design techniques and initial testing has demonstrated design objective conformance.
