不同型号侧扫声呐分辨能力和扫宽能力的比较分析

侧扫声呐是海洋科学调查中常用的仪器设备,针对此类声学探测设备出台相关检测、检定等计量化的标准势在必行。本文介绍了侧扫声呐的工作原理和技术参数,针对侧扫声呐分辨能力和扫宽能力这两个性能指标,提出了一种评价方法。最后通过海上试验,对比分析了3种常用的侧扫声呐仪器的分辨能力和扫宽能力,为侧扫声呐系统的选用和引进提供参考。

Comparison and Analysis of Different Types of Side Scan Sonar's Detection and Scan Width Ability

side scan sonar is widely used in marine scientific investigation, it is vital to promulgate standards for testing and verification of such acoustic detecting equipment. This paper introduces the working principle and technical parameters of side scan sonar. In this paper, an evaluation method is proposed for the detection and scan width ability of side scan sonar. At last, the paper compares and analyzes three kinds of commonly used side scan sonar's detection and scan width ability. It provides reference for selecting and intro-ducing the side scan sonar system.
