In this thesis, two key-techniques of high-resolution imaging sonar are studied: beam-forming and acousticalimage processing.
论文对高分辨率成像声纳的两个关键技术：波束形成技术和水声图像处理技术进行了研究。

It also gives an introduction to the malfunction and its debugging when locating the quality index of the acousticalimage graphics.
还介绍了检定B超的声像图质量指标常见故障及排除方法等。
