Latest Patents

Xiaodong Cui's latest patents include a sediment classification method and system based on bottom echo information of deep-sea multibeam water column. This invention falls within the technical field of seabed sediment classification. The method extracts multidimensional features of seabed multibeam time series using multibeam water column data. It constructs features of seabed spots by fusing an angle response curve. The process involves double-waveform spectrum comparison of original sample point waveforms with seabed measured point waveforms. By using Cosine Similarity, two groups of corresponding waveforms are matched to expand original sample points, thereby improving the reliability of classification results. This innovation realizes the transformation from hard to soft classification and further enables seabed habitat inversion of complex mixed sediment in deep-sea environments.

Another notable patent is a device and method for detecting main acoustic indexes of multi-beam sonar. This invention pertains to hydrographic surveying and charting technology. The device includes a rotating device and a lifting gear installed in an anechoic tank. It features a multi-beam sonar that transmits signals along the horizontal direction. A standard hydrophone is connected to a signal collector, allowing for the detection of frequency, source level, and beam angle of multi-beam sonar.
