Surface-Duct Sonar Measurements (SUDS I - 1972) Propagation Loss Measurements. Volume I. Instrumentation and Data Reduction Procedure.
Abstract
During 9-24 February 1972 a series of 18 propagation loss experiments were conducted in three deep-water areas located southwest of San Diego, California. These measurements were designed to measure near-surface continuous wave (CW) pulse propagation losses and propagation losses for explosive sources out to ranges of 45 kyd and to obtain detailed supporting environmental measurements. Measurements were made at CW frequencies of 0.4, 1.0, 1.5, 2.5, 3.5, and 5.0 kHz. The explosive measurements were analyzed at 0.40, 0.63, 1.00, 1.60, 2.50, 3.15, 5.00, and 10.00 kHz. This report contains the propagation loss measurements. It consists of five volumes. Volume I describes the instrumentation used to make the propagation loss measurements and the data reduction procedures. Volumes II-V are detailed reports containing a summary of the environmental measurements, plots of propagation loss versus range, and comments pertinent to the specific propagation loss run.
