Effect of Temporal and Spatial Environmental Variability on Littoral ASW Search Tactics
1998
Delbalzo, Don
My long-term goal is to better understand the temporal and spatial impact of oceanographic and meteorological dynamics on Navy sensors, systems, and operations. The current world political situation has resulted in increased emphasis on naval operations in littoral (usually shallow water) regions. However, current ASW sensor/system prediction systems and tactics are still heavily biased toward relatively homogeneous, deep-water areas where sea-bottom properties and temporal variability are not dominant factors. There is a requirement to improve shallow-water operations, including better search planning and tactics development in range and azimuth dependent environments, especially when weather variations and currents mitigate against a frozen ocean assumption. The objective of my FY98 effort was to examine the sensitivity of acoustic processes and sensor performance in the littoral zone to temporal environmental variations. A key question to be addressed is How much better is a tactic based on nowcast sound speed profile (SSP) data using in-situ measurements (e.g., drifting buoy thermistor data) compared to archival GDEM data (climatology)? Conceptually, this is illustrated below.
