【摘要】 针对水下堤坝安全检测,提出并设计实现了适合水下机器人等小平台为载体的可用于堤坝安全检测的高分辨率剖面声纳,系统通过获取被测堤坝内部的回波信号,由DSP构成的水下处理单元进行实时信号处理,从而可获得坝体内介质不连续的信息,并由水上分机进行堤坝内部剖面图像的重建及显示。通过水池和外场堤坝工程检测等应用实例,取得了良好的效果,验证了系统技术路线的可行性和性能的稳健性。更多还原

【Abstract】 For the inspection of the dam safety,a high resolution chirp sonar based on underwater robot is proposed and designed.The system acquires the reflected signals from the inside of the dam because of the discontinuity,after the correlation processing by the digital signal processor.The PC in surface unit makes the profiling image reconstruction and display.This system gets favorable effects through the experimentations of pool and outfield.更多还原
