The high-resolution sector scanning sonar image based underwater topographic survey 基于高分辨率扇面扫描声纳影像的水下测量
Image Building and Features Extraction of Forward-looking Scanning Sonar 前视扫描声纳的成像与目标特征提取
This paper studies these two aspects in detail. Frequency changing and equivalent sampling were applied to solve the running accuracy of the scanning system and the problem of very high speed sampling. Equivalent sampling technique can also be applied to the acquisition of Radar and Sonar signals. 使用变频与等效采样技术,解决了坐标系统的运行精度及超高速数据采集的问题,其中等效采样技术也适合于雷达、声纳信号的采集。
