Researchers at Draper, MIT have developed a passive acoustic remote sensing method for unmanned underwater vehicles, says an article published in Yahoo Finance.
Acoustic Signature in UUVDetecting the presence of an unmanned underwater vehicle (UUV) is usually achieved by intercepting the noise radiated by its propeller. In a noisy harbor, this task is hindered because the acoustic signature of a UUV and the noise in the local environment often present too much signal complexity for current...
