中文摘要:
      针对矢量水听器自噪声测量时受环境干扰严重的问题,提出了利用双通道传递函数法测量矢量水听器的自噪声。给出了双通道传递函数法降低环境干扰的原理;并通过实验手段分析了利用该方法测量时,环境背景噪声条件及水听器布放距离等因素对测量结果的影响。研究结果表明,利用双通道传递函数法测量矢量水听器的自噪声,可以有效降低环境背景噪声影响,得到更加准确的结果。该方法为准确测量矢量水听器的自噪声提供了有效的手段,为矢量水听器在远程探测领域的实际工程应用提供了测量基础。
英文摘要:
      The vector hydrophone is seriously disturbed by the environment interferences when measuring its self-noise, so the dual-channel transfer function method (DTFM) is proposed for solving this problem. First, the principle of DTFM to reduce the environmental interference is analyzed. Then the factors affecting the measurement, such as the background noise condition and the spacing of the dual hydrophone, are researched by means of the experimental method. The results indicate that the self-noise of the vector hydrophone can be satisfactorily measured by using DTFM:not only the environmental interference can be reduced effectively, but more accurate results can be obtained as well. DTFM provides an effective approach to accurately measuring the self-noise of vector hydrophone, which supplies a measurement basis for the practical engineering application of vector hydrophone in the field of remote detection.
