Thermoacoustic bi-static sonar system |
摘要 |
This invention is a thermoacoustic sonar system for detecting a target that is located at or beneath the surface of the water. The foregoing system comprises a laser or particle accelerator that is located above the water and a plurality of passive receivers that are located on or above the water. The laser produces a light beam whose amplitude is subsequently modulated or whose pulses are varied in time. A particle accelerator would produce a pulsed particle beam that varies in time. These modulated or varied pulses are focused or deflected to a small layer of water at the air/water interface so that the beam will be absorbed by the water causing the water to produce an acoustic signal that may propagate to a target where the acoustic signal will be reflected and possibly detected by one or more passive receivers.
