Abstract:

During the interval March 1977 through February 1980, members of the Valley Forge Research Center technical staff have been investigating coherent operation of large underwater acoustic arrays, taking account of the dispersive effects of the medium. Array organizations of two kinds were investigated. The first of these is a very large array comprised of conventional subarrays, the total extend being in the order of hundreds of miles. Most of this work was carried out during the first two years of the project and resulted in a doctoral dissertation. The second system studied is an array of submerged sensors, suspended from freely floating buoys and randomly dispersed over an area of the order of 500-1500 meters in diameter in this case, therefore, element positions are continually changing. Work on the latter array system was distributed over the entire duration of the project. The results of the study were published in quarterly progress reports of the Valley Forge Research Center and in other publications. We present below a summary of our activities and results along with applicable excerpts from our reports and copies of a published paper and a dissertation. Additional papers for publication, drawn from the material presented here, are in preparation. Author
