Hydrophone Calibration Based on Microcontrollers for Acoustic Detection of UHE Neutrinos.

Abstract—This paper discuses hydrophone calibration for generation of artificial Ultra High Energy (UHE) neutrino-induced pulses. Signal processing techniques are applied to hydrophone modelling. A bipolar acoustic generation module is built using PIC microcontrollers for processing and control. The NI-USB6211 commercial module is used for comparison. The modelling is compared to experimental data generated in a laboratory water tank. The result from simulation and experiment are compared showing excellent agreement. This opens the way to excite steerable hydrophone arrays which is not possible with current hardware. Keywords—Hydrophone calibration, Acoustic detection, UHE neutrinos, Microcontroller
