Calibration of HLF-3 Low Frequency Hydroacoustic Source.
Abstract
Calibration results of an underwater sound source are described. This source produces source level of 198 dBu 1 microP a at 1m at 210 Hz and has an output exceeding 193 dB over the band from 170-310 Hz. It contains an integral hydraulic power supply and hydroacoustic amplifier and requires no electronic power amplifiers. The calibration data include Transmitting Response (100-600 Hz) , Polar Patterns, Output Spectra, and PUlse Photographs. Data are included for both 99 feet and 323 feet depths (the source is rated for 1000 feet without pressure compensation).
