摘要
压电陶瓷水听器在水声信号检测应用中有着广泛的应用,其极性直接关系到水声信号的相位信息,决定了水声采集数据的质量。文章提出了一种用于压电陶瓷水听器极性检测的方法,该方法通过计算机控制激励模块(测试盒)产生主动式测试信号源,并配合极性测试算法分析水听器所采集到的波形信息,判断出水听器的极性。测试结果表明,该方法能够快速有效地对待测水听器极性做出准确判断,且简单可靠,可广泛应用于水声信号检测领域中。
Piezoelectric ceramic hydrophones are widely used in underwater acoustic signal detection.Their polarity is directly related to the phase information of the underwater acoustic signal,thus determining the quality of the underwater acoustic data.In this paper,a method for polarity detection of piezoelectric ceramic hydrophone is proposed.The method generates an active test signal source through a computer controlled excitation module,and uses the polarity test algorithm to analyze the waveform information collected by the hydrophone,so the polarity of the hydrophone can be determined.The test results show that the method can rapidly and accurately determine the polarity of the hydrophone.The method is simple and reliable,and can be widely applied in the field of underwater acoustic signal detection.
