摘　　要：介绍Teledyne Benthos TTV-301声学深拖系统的构成、海上作业模式以及声学数据获取方式,以南海某海域实测声学数据为例,对获取的多波束水深数据、侧扫声呐数据、浅地层剖面数据进行精细处理,获取高质量的水深图像、高分辨率的侧扫声呐图像和高精度的浅地层剖面图像。对同一海底微地形微地貌在不同声学影像上的反射标识进行对比分析,建立声学3D模型,形成海底浅表层的立体探测。实验结果验证了声学深拖系统在海底微地形地貌调查中的有效性与可行性,并可取得理想的效果。This paper introduces the structure, operation and acoustic data acquisition of the deep tow system in detail. The high resolution sonar image, and high quality water depth image sub bottom profile image are generated by the data processing, then a comparative analysis is made of the reflection marks of the same seabed microtopography in different acoustic images. A 3D model is established to from a three- dimensional exploration of the surface of the sea floor. The result verifies the effectiveness of the deep tow system and shows the acoustic image meet the needs of the seabed microtopography survey.
