EXPERIMENTAL EVALUATION OF THE EFFECT OF OCEANOGRAPHIC PARAMETERS ON SUBMARINE SONAR PERFORMANCE (U)

摘要

The results of measuring the effects of environmental variables on acoustic transmission in the ocean are summarized in this report. The environment variables were measured both before and during a controlled-geometry submarine exercise, using sensors on a research vessel and an aircraft. The acoustic signals were obtained from the submarines. During the submarine exercises, the SUBIC DDP-24 computer was used to predict the best listening depths for each run, using the most recent sound velocity profile data measuring from the submarine as the input to a ray-trace program. The interpretation of the acoustic signals in the context of the measured environmental variables is the major result of this report. (Author)
