Abstract

Due to the obstacles to underwater acoustic transmission such as narrow bandwidth and frequent data loss, a novel time-domain signal compressing-reconstruction method is proposed for underwater inclination data transmission of a multi-point mooring system. First, a time-frequency analysis was carried out on the measured inclination data and a calculation method using the top tension force of the anchor chain was proposed. Then, to address problems like narrow bandwidth and easy data loss, a time-domain signal compressing-reconstruction algorithm was constructed. The data indicated that the reconstruction error was only 0.6957% with a compression ratio of 20%. Finally, the effects of compression ratios and loss rates on the reconstruction accuracy was analyzed to demonstrate the accuracy, feasibility and reliability of the compression-reconstruction algorithm.
