A computerized data acquisition system intended to completely automate the evaluation of underwater acoustic materials in the environment of a waveguide has been designed by the David W. Taylor Naval Ship Research and Development Center, Annapolis, Maryland. The system utilizes software sampling a technique whereby the complete time-varying, analog representation of an acoustic signal is converted into digital format by means of a digital oscilloscope and then transferred to a computer where it is processed under program control. Data reduction occurs simultaneously with data acquisition and is obtained in hard-copy format as well as in graphical form. Measurements, such as reflection loss, energy absorption, target strength reduction, and acoustic impedance, are incorporated into the system through software creation and require no additional hardware subsystems.
