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

Abstract

The invention provides a multi-modal sea wave prediction system for a small sea area, comprising: a plurality of multi-spectral remote sensing devices arranged at the center of the sea area view fieldto collect a wave large view field image; a velocity direction meter and a heave accelerometer are both placed in the center of the field of view of the sea area, and measure the velocity direction and amplitude of the waves when they are actually pushed to the center of the field of view. The upper computer is signally connected with the multi-spectral remote sensing instruments, the velocity direction instrument and the heave accelerometer to process the ocean wave image collected by the multi-spectral remote sensing instrument, and calculate the time and the changing trend of the single sense wave arriving at the center of the field of view in the field of view. At the same time, the host computer also measures the wave velocity, wave direction and wave height in the center of the field of view according to the current direction meter and heave accelerometer, optimizes the prediction algorithm of wave parameters, and improves the prediction accuracy. The invention also includes a wave prediction method. The invention provides timely and effective early warning service for marine activities, has high prediction accuracy and 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...
