Latest Patents

One of Grande's latest patents is titled "System and processor for real-time extraction of ocean bottom properties." This system characterizes ocean bottom properties in real-time by exploiting the multipath structure of reverberation. It extracts values for bottom loss and the bottom scattering coefficient. The system synchronizes environmental and navigational data with sonar state data and acoustic beam data to produce an input data stream for an extraction processor. The extraction processor utilizes digital signal processing to create a reverberation energy envelope from the acoustic beam data. It time correlates this envelope with the environmental, navigational, and sonar state data. A general-purpose computer monitors these parameters for changes and instructs a modeling processor to construct new eigenray propagation and reference reverberation models as needed.

Another significant patent is the "Method for real-time extraction of ocean bottom properties." This method also characterizes ocean bottom properties in real-time by analyzing the multipath structure of reverberation. It extracts bottom parameters from a measured reverberation energy envelope generated by sonar system returns. The measured envelope is compared to a reference model to identify periods suitable for parameter extraction. The accuracy of the reference model is maintained by continuously monitoring sonar state configurations and environmental parameters, ensuring that any changes are accounted for in the model.
