High-Fidelity Finite-Element Modeling of Shallow-Water Target Scattering
The goal of this three-year effort is to develop a state-of-the-art, high-fidelity, finite-element, broadband computer simulation capability for modeling the scattering of sonar signals by undersea mines located in or near the seabed in littoral environments with smooth or rippled water/sediment interfaces. The target models will include all internal and external structural details that signifi...
متن کاملBistatic Scattering from Buried Targets in Shallow Water
The development of new concurrent detection and classification concepts has the potential of dramatically increasing the coverage rate of shallow water mine countermeasures, in particular for buried targets. The GOATS'98 experiment had as one of its main objectives to explore the possibility of basing such a concept on the measurement of classifying features of the 3-D acoustic scattering by su...
متن کاملSeafloor Scattering in Shallow-Water Environments
Mud volcanoes are solid objects that form on the seafloor due to the emission of gas and fluidized sediment from the earth’s interior [1]. They vary widely in size, can be exposed, proud, or buried, and are of interest to the Navy as sources of active sonar clutter [2]. The long-term goal of this work is to accurately model mud volcano scattering. The final product will make predicting and simu...
متن کاملTarget Strength Measurements in Shallow Water
A submarine on patrol needs to know how far it can be detected by active sonar. In order for such sonar performance calculations to be useful the target strength (TS) of the submarine must be known. Measurements done in deep water indicate that TS can vary as much as 20 dB as a function of aspect angle. This corresponds to a doubling of the detection distance in a noise limited environment, and...
متن کاملMeasurements and Modeling of Acoustic Scattering from Unexploded Ordnance (UXO) in Shallow Water
Introduction: The gradual development of coastal areas throughout the world in proximity to military training ranges and areas of past conflict has created a need to locate underwater unexploded ordnance (UXO). These ordnance, which may have veered off course and failed to detonate when they were initially released, may still pose a risk of explosion if they are subject to handling. This compli...
