Preliminary Analysis of a Vertical Sonar Array to Measure the Fine Structure of the Thermocline.
Abstract
An active sonar system with a large horizontal array has been considered as a means of measuring the fine structure of the thermocline. The array is required to provide the processing gain necessary to distinguish the sonar backscatter of the horizontal fine structure from the biological backscatter. In the system described, the active sonar signal is directed obliquely at the thermal sheets and the forward-reflected energy is monitored with a simple vertical array. The obliquely-reflected intensities are 80 to 90 dB greater than the perpendicularly-reflected backscatter, so that a large array is not required. (Author)
