An underwater acoustic marker was designed based on Braille design concept,and the ima-ging 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 con-crete backing is slightly higher than that of steel backing.Furthermore,the marker image is en-hanced,and the imaging quality is improved by 2.85 times,which greatly improves the difficulty of judging the target characteristics of acoustic images.
