Array Receivers and Sound Sources for Three Dimensional Shallow Water Acoustic Field Experiments

Abstract

The approach of the instrument upgrade included improving the SHRU clocks by utilizing chip-scale atomic clocks (CSAC), enlarging battery packs to extend the operation duration, and adding data storage capacity for long-duration missions. The advantage of CSAC on clock precision can improve synthetic aperture processing and ocean acoustic tomography and achieve excellent long-term timing precision. A one-year deployment with continuous recording can be accomplished in the Arctic Ocean acoustics experiment, to capture both summer and winter conditions. Besides the hardware upgrade, we also improved the software controlling the SHRU data acquisition systems. After the hardware and software upgrades, the SHRU units were placed in a cooler at 0 degrees Celsius for comprehensive system testing.
