Abstract : The objective of this project was to evaluate the performance of surface acoustic wave (SAW) oscillators for potential application to SAW sonobuoys. The tests included the following: (1) oscillator frequency and time domain stability, (2) static loading sensitivity tests, and (3) underwater sensitivity and frequency response tests performed on a SAW hydrophone feasibility model. In summary, the results show that the SAW sensor is comparable in sensitivity to hydrophones currently available, typically -180 dB re 1V/uPa.
