Underwater Acoustic Testing
Tools to Evaluate Sonar System and Counter Measure Performance, and Conduct Research and Training
Underwater acoustic testing typically involves the generation of complex signal configurations that mimic the acoustic signature of a ship, submarine, or torpedo.
Any application requiring underwater acoustic generation or underwater vibration generation can be performed with SignalSound exciters. Data Physics can provide turnkey underwater acoustic testing systems for applications ranging from mine sweeping to oceanographic research.
Acoustic Range Calibration
Acoustic range calibration, or acoustic ranges, is used for the measurement of a vessel’s acoustic signature so that mechanical defects that enhance that signature can be eliminated. The calibration of these ranges requires accurate, wideband projector systems with a low frequency capability.
Data Physics SignalSound calibration system has a very wideband capability with excellent beam patterns for the calibration of acoustic ranges and acoustic data gathering installations.
Sonar Signal Generation and Measurement
Data Physics SignalSound systems are able to generate all the narrow band lines, broad band noise, modulation effects and transients that are associated with the acoustic signatures of ships and submarines. SignalSound can also generate sonar pulses as an echo repeater to interact with active sonar.
Sonar Training
Sonar training is performed principally for the operators of passive sonar so they can learn to identify the acoustic signatures of submarines and ships, to be able to differentiate between different platforms, and to be able to track and prosecute a target. Data Physics can offer a range of towed acoustic targets, static targets, and acoustic enhancements for ships and submarines to augment their normal signature.
Mine Sweeping
Mine sweeping involves detecting and disposing mines, and a minesweeper is a naval warship designed to negate the threat posed by naval mines. Data Physics produces a high power, very low frequency acoustic projector system that may be used as part of a combined sweep or multi-influence sweep system. These signal generators and underwater noise generators are designed to include long term operation and survivability.
