Abstract: An adaptive tracking system and tracking method for a water surface target are provided. The tracking system includes an information acquisition module, a mode selection module for controlling a tracker to enter a tracking mode or a prediction waiting mode, a tracking module for controlling the tracker to track the water surface target, a prediction module for generating a predicted position of the water surface target, and a wake-up module for waking up the tracking module when the water surface target appears at the predicted position. The mode selection unit is introduced, which controls the tracker to enter the prediction waiting mode when the water surface target is occluded or greatly affected by an adverse environmental factor. The design avoids the tracker moving away from the water surface target in a wrong direction, thereby avoiding adverse effects on subsequent tracking of the water surface target.
