Mid-Frequency Towed Acoustic Array
Abstract
Proposed is the acquisition of a mid-frequency towed acoustic array and tow cable. The towedarray will consist of 64-elements in a" nested design corresponding to 33-elements with a halfwavelengthspacing at 6 kHz (0.125 m), 33-elements with a half-wavelength spacing at 3 kHz(0.25 m), and 32-elements with a half-wavelength spacing at 1.5 kHz (0.5 m). The overallacoustic aperture will be 15.5 m. The array will be capable of receiving in the 0.1-40 kHzfrequency band (although its predominant use will be for 0.5-10 kHz data collection purposes)with 24 bit A/D conversion. Included are 2 non-acoustic sensors at the head and tail of the arraythat measure heading, pitch, roll, temperature, and pressure/depth. Telemetry of the digitizedarray data up the tow cable will be via 100 Mb/"s or 1 Gb/s Ethernet.
