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.
