障碍物探测方法探讨

Discussion on the Method of Obstruction Survey

介绍了侧扫声纳、多波束测深系统、磁力仪的工作原理,提出了障碍物探测的相关技术要求。实例分析了综合利用侧扫声纳、多波束进行沉船探测的方法,结合侧扫声图和多波束水深探明障碍物的精确位置,测得最浅点水深,全面获得障碍物信息,大大提高了探测质量。对铁磁性小目标探测能力进行评估,并用实例加以分析和佐证。

In this paper, the principles of side scan sonar, multibeam echosounding and magnetometer were introduced. The technical requiremnts of obstruction survey were provided. Examples illustrate survey method of comprehensive application of side scan sonar and multibeam echosounding. The accurate position and the lowest depth could be obtained by comparing the side scan sonar image and multibeam sounding data. Comprehensive information of obstructions greatly improve the quality of survey. The assessment on capability of detecting the small magnetic object was also presented. Details analysis were shown by example.
