The present invention relates to a sub-bottom profiler to analyze the structure of a seabed using sound waves. The present invention provides a hull-mounted sub-bottom profiler system allowing leveling; and the sub-bottom profiler system and the methods of the related art are subject to the problems of sub-bottom profiler impairment or loss due to the obstacles such as fisheries which has resulted in the costs for equipment repair, replacement, and time damage due to equipment recovery; as the sub-bottom profiler is pulled while hung to the back of a ship or is used mounted on the side surface of the hull using an installation frame. However, in accordance to the present invention, a space is formed in the vicinity of the center of a lower end of the ship, and a sub-bottom profiler installation box is produced such that the sub-bottom profiler is mounted on the space to prevent damage or loss due to fisheries or obstacles. Also, shaking due to waves or tides is reduced while the bottom surface of the box is formed of an FRP material such that the transducer is not exposed outside, and the transducer can be protected. The transducer and the bottom surface are completely sealed such that no space is formed between the transducer and the bottom surface, which allows noise to be reduced. In addition, the inner space of the box is filled with seawater such that the profiling can be performed in the environments identical to the external environments, and the sub-bottom profiler can be leveled without any restrictions. |
