摘　　要：为了实现水下声信号的遥感探测，针对水下声信号光电探测技术的强度调制理论，提出了光线分析理论模型，并进行了初步的理论分析和实验验证，取得了频率为65Hz和100Hz的水下声信号的探测数据，验证了水下声信号光电探测技术的强度调制理论。实验结果表明，在空气中利用激光，在水中利用声波，通过这两种信号载体来探测水下声信号技术是可行的，这一结果对于水下声信号光电探测技术的研究具有一定的参考价值。In order to achieve the remote sensing of underwater acoustic signal, a model of beam analyzation method was presented for the intensity modulation theory of photoelectric detection of underwater acoustic signal. A preliminary theoretical analysis and experimental verification were made and underwater acoustic signal detection data was achieved at the frequencies of 65Hz and 100Hz. Experimental results show that it is feasible to detect underwater acoustic signal with laser in the air or with underwater acoustic wave, which is valuable for underwater acoustic signal detection.
