A measurement technique has been developed which makes possible the determination of the acoustic transmission loss for various paths between a source and a receiver at relatively short ranges in the ocean. The method is based upon a technique called Time Delay Spectrometry (TDS). The theory for utilizing TDS to perform measurements on an underwater test range with a homogeneous water column is presented. The experimental parameters concerning test geometry together with criteria for the source signal are discussed and the limitations are described. A computer program written in HP BASIC is the tool in a multipath measurement system where analog sound signals recorded on tape are processed by an HP 356A Dynamic Signal Analyzer under program control. Originator-supplied keywords include: Time Delay Spectrometry (TDS), Under water acoustic propagation, Dynamic signal analyzer, Linear frequency modified pulse (LFM pulse).
