摘要
为了检验光纤水听器阵在低频(100Hz^1kHz)/甚低频段(<100Hz)的测量性能,在南海海试中,我们将一16元光纤阵与16元常规压电水听器阵平行安装在同一基阵框架上并沿舷侧布放,使得两阵受到基本相同的振动干扰。通过单频和宽带脉冲信号的传播实验,对双阵接收信号进行比较。试验结果表明,光纤阵具有更好的抗振动加速度性能,因此在甚低频段检测中具有明显的优势。
In order to testify the low and very low-frequency performance of Fiber Hydrophone Array （FHA）, a 16-elements FHA and a 16-elements Piezoelectric Hydrophone Array （PHA） are installed symmetrically on the same framework, so enduring almost the same vibration interference. Compared with the received signals during the CW and broadband pulse propagation experiment in our 2008＇ South-China Sea Trial, the Fiber array shows more endurance for vibration acceleration and has significant advantage in the very low-frequency signal detection.
