Abstract
Laser remote sensing underwater acoustical signal is one effective way to recognize underwater targets and realize on-board active scanning, acquisition, pointing and tracking over a wide range. By the research of the theoretical and the simulation of PC, one fundamental experiment system is constructed, which validates the feasibility of laser detection of underwater acoustic signal. The size and location of the diaphragm of the detection system are particularly discussed and one optimum diaphragm aperture was developed. The affection of the incidence beam width is also analyzed. By selecting the very incident angle and beam width, we can get the best performance. These conclusions has the important guiding significance to the technology of laser remote sensing underwater acoustic signal. As a whole laser remote sensing underwater acoustic signal has its own advantages and opens up broad possibilities for the practical application. Of course it still has something to do to improve its performance, which worth doing further studies.
