3" Sonar Countermeasure

The Phase I Base effort concluded with an FEA model that was validated with a hardware demonstration of the low frequency transducer channel and a baseline design for the power amplifier. The Phase I hardware demonstration validated the feasibility of the base design when coupled with textured ceramic and high frequency SiC based power amplifiers.  Building on the successful Phase I, QorTek plans to upgrade the Phase I generated designs and trade-off design parameters between the ceramic, transducer and electronics design to facilitate overall optimization of the ADC system. The transducer suite will be coupled with a high-performance power amplifier design based on previous Navy underwater programs to result in a lightweight compact 3" MK 4 sonar countermeasure that significantly reduces its present size and weight.  This compact ADC solution will be built and undergo extensive test evaluations of its low frequency and high frequency transducers channels. The Phase II will conclude with a complete 3" MK 4 sonar countermeasure design that has been acoustically validated, environmentally tested and exposed to a mock countermeasure launch.
