【摘要】：针对浅地层剖面仪和侧扫声呐这2种声呐系统探讨性地提出了"两步法"的性能检测和评价方法:1)声学物理参数检测:分析了与浅地层剖面仪和侧扫声呐系统性能相关的关键声学物理参数(声源级、频率/频谱、脉冲长度、波束角或开角),并提出了在消声水池中测定这些参数的方法;2)实际探测性能评价:分析了与浅地层剖面仪和侧扫声呐系统性能相关的实际探测效果评价指标,并提出了通过海上试验来检测和评价这些指标的方法。最后对建设具备高效消声性能的大型试验水池,建设海底标准地层检测场和海底标准目标物检测场以真正实现设备性能的检定应做的后续工作进行了讨论。
[Abstract]:In this paper, a two-step method is proposed to detect and evaluate the performance of shallow stratigraphic profiler and side-scan sonar systemically. 1) Acoustic physical parameter detection: analysis of sonar system compared with shallow layer profiler and side-scan sonar system. Key acoustic physical parameters related to the performance of the system (sound source level, Frequency / spectrum, pulse length, beam angle or open angle), and a method for determining these parameters in a silencing tank is proposed. 2) actual detection performance evaluation: the evaluation indexes related to the performance of shallow stratigraphic profiler and sidescan sonar system are analyzed, and the method of detecting and evaluating these indexes by offshore test is put forward. At last, the following work is discussed in order to realize the verification of equipment performance, such as the construction of a large experimental pool with high efficiency and sound attenuation, and the construction of a seabed standard stratum detection field and a seabed standard object detection field in order to truly realize the verification of the equipment performance.
