A Surface Acoustic Wave (SAW) Pressure Sensor Evaluation
1980
Staples, E. J.
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.
