APPLICATION OF THE NEAR-FIELD-ARRAY TECHNIQUE TO SONAR EVALUATION

Abstract

The design, construction, and step-by-step tests of the near-field array as it has been developed at the Underwater Sound Reference Laboratory are described. The optimum design and design tolerances for several arrays have been found by means of a digital computer. A guide for estimating the cost of an array for application to a particular sonar evaluation is derived from experience in the construction of these new arrays.
