Next Generation Depth Sounder
Abstract
The first part of this report describes continued technical monitoring of the AN/UQN-1,4 retrofit kit procurement. The second item covers work on developing a high frequency transducer for the Next Generation Depth Sounder (NGDS). Two preliminary designs are to be tested. One is a 7-element mosaic of 7/8 in. ceramic discs arranged in a circular pattern, with a center element surrounded by six outer elements. The other is a 3 in. diam ceramic disc that is diced by cutting part way through the element of a rectangular grid pattern. A housing for these elements will consist of a standard AN/UQN-4 transducer housing that will also contain six mass-loaded 12 kHz elements of a type already used by the AN/UQN-4. The 12 kHz elements will surround the centrally located high frequency element. Preliminary efforts have been directed toward obtaining acoustic signal and noise data from AN/UQN-4 depth sounders to ascertain the operating environment within which the signal processor must function.
