Error Processing Techniques of Integral Velocity Based on Frequency Spectrum Forecasting

Abstract:

The integral velocity error at the head end and the tail end of wave movement of ships or offshore platforms are too great. By improving the forecasting technique based on frequency spectrum, the integral velocity errors are maximally corrected and the wave movement of ships or offshore platforms is successful forecasted longer time ahead of time. Measurement technique of ship wave movement based on accelerometers array will be practically used.
