摘要
以DSP和ADC为硬件核心,采用3×3解调算法,研制了光纤光栅水听器信号解调系统.该解调系统具有体积小,调试方便,解调输出信号质量好,幅度稳定,工作带宽宽等特点.实验证明,该解调系统能很好的在30 Hz^160 kHz的带宽范围内工作.
A fiber Bragg grating hydrophone signal demodulation system is developed based on DSP, ADC and 3×3 signal demodulation method. The demodulation system has small body and is easy to use. It outputs signal with stable amplitude and good quality. It is proved by experimentations that the demodulation system can work well beyond 30 Hz~160 kHz frequency range.
