A Technique for Sonar Data Processing.
Abstract
In the command and control portion of the ASW Hydrofoil feasibility study requirements for sonar detection and tracking were postulated. The problem of extracting information from the sonar signal returns for tracking purposes were intensified by the high target closing rates, the modest sonar ranges and attendant high ping rates, and the need to provide multiple-target-tracking capability. The data processing rate took incremental steps as these requirements took form. Although certain aspects of the LORAD, SPADE and ASIAC developmental sonar data processing systems are probably applicable, as further study may show, none of these as a system fully satisfy the ASW Hydrofoil sonar data processing requirements. It has been established that a coherent detector (matched filter) will be used in the sonar system, and its characteristics are well known. Consequently, beginning with its output the subsequent sonar data processing specifications are to be determined, as well as the design approach required to meet these specifications. The following discussion will attempt to give some insight into this particular problem.
