| 中文摘要: |
| 本文分析了干涉型光纤水听器内调制相位载波(PGC)调制解调的原理,提出了PGC调制解调的全数字化方案,通过计算机仿真,并在光纤水听器系统中实现了PGC的数字化解调。实验室光纤水听器与标准水听器对比测试以及实际海况试验都证明,数字化PGC解调技术在光纤水听器系统的实现对水声信号的检测是有效的。 |
| 英文摘要: |
| In this paper we analyse the principle of phase-generated carrier (PGC) modulation of interferometric fiber optic hydrophone, then put up a scheme to realize PGC demodulation by digital scheme, perfect it by lots of simulations on computer. We validate its effectiveness by comparing a signal from a fiber optic hydrophone with one from a standard hydrophone, and by a long-distance seatest using an all optical fiber optic hydrophone array. |
