【摘要】 侧扫声纳图像由于受到船速、海底地形、波束指向性、噪声等因素的影响产生了变形,如果不进行改正,会严重影响资料解释的准确性。本文分析了侧扫声纳图像变形的种类和原因,在此基础上提出了新的改正方法。实际数据处理结果显示,本文方法有效消除了侧扫声纳图像的变形,这为进一步的处理以及解释打下了良好的基础。
【Abstract】 The side-scan sonar images are often distorted because of the speed,the seabed topography,the beam directivity, noise and other affecting factors.If the distortions weren’t eliminated,it would affect the accuracy of side-scan sonar image interpretation.Based on the analysis of the types and causes of the image distortion,the paper introduces new methods to remove the distortion.The processed results of the actual data show that this method can remove the distortion of image, which has laid a good foundation for further processing and interpretation.
