摘　　要：文中基于盲文设计理念设计一种水下声学标识物,并构建成像质量评价标准,结合水下模型实验对标识物的成像效果进行分析.结果表明:标识物可在声学图像上呈现出清晰的标识信息;成像质量随目标距离的增加而下降,随声呐扫测范围的提高而上升;混凝土背衬的成像质量略高于钢铁背衬的成像质量.进一步对标识物图像进行增强处理,成像质量提高2.85倍,极大的改善了声学图像目标特征的判断难度.An underwater acoustic marker was designed based on Braille design concept,and the imaging quality evaluation standard was constructed.The imaging effect of the marker was analyzed in combination with underwater model experiments.The results show that the marker can present clear identification information on the acoustic image.The imaging quality decreases with the increase of target distance and increases with the increase of sonar scanning range.The imaging quality of concrete backing is slightly higher than that of steel backing.Furthermore,the marker image is enhanced,and the imaging quality is improved by 2.85 times,which greatly improves the difficulty of judging the target characteristics of acoustic images.
