A small-scale sea area multi-modal wave forecasting system and its forecasting method

Abstract

The invention provides a small-scale sea area multi-modal wave prediction system, which includes: several multi-spectral remote sensors placed in the center of the sea area field of view to collect large field of view images of waves; a flow velocity and direction meter and a heave accelerometer, both placed in At the center of the sea area field of view, the flow velocity, direction and amplitude of the single meaningful wave are measured when it actually advances to the center of the field of view; the host computer connects the signals to the several multi-spectral remote sensing instruments, flow velocity and direction meters and heave accelerometers to process multiple The wave images collected by the spectral remote sensing instrument can be used to calculate the time and changing trend of a single significant wave within the field of view to reach the center of the field of view; at the same time, the host computer also actually measures the wave speed in the center of the field of view based on the flow velocity meter and heave accelerometer. , wave direction and wave height, optimize the wave parameter prediction algorithm and improve the prediction accuracy. The invention also includes a wave prediction method. The invention provides timely and effective early warning services for marine activities, has high prediction accuracy and has good practical value.

Description

technical field [0001] The invention relates to the technical field of sea wave disaster prevention, in particular to a multi-mode sea wave prediction method in a small-scale sea area. Background technique [0002] Wave disaster prevention can be directly used in marine economic activities. When ocean transportation, marine scientific investigation, offshore oil development, maritime military activities, and aquaculture activities are affected by waves, serious disasters will be caused to marine activities. Efficient and reliable wave detection and prediction technology can effectively prevent sudden wave disasters and is an important guarantee for marine economic and military activities. [0003] At present, wave monitoring and forecasting technology mainly uses traditional observation methods combined with statistical theory to obtain and forecast wave information. Most of the wave information forecast is wave spectrum formed by large-scale statistical data. However, smal...
