"Development of a Cardioid Sensor for Conformal Hull Arrays"
Submarine hull arrays utilizing CAVES technology require thick compliant
baffles to isolate the acoustic sensor from self-noise. These compliant
baffles compress with depth, resulting in significant ship impact.
One means of eliminating the need for thick baffles is through the use
of directional sensors which have little or no response in the backward
This thesis presents the development of a cardioid sensor, along with the necessary shading coefficients, which null hull flexural waves. Both theory and measurements are presented.
