Marine ship target analysis method based on image and electronic reconnaissance fusion

The invention belongs to the technical field of ship track data processing, and discloses a marine ship target analysis method based on image and electronic reconnaissance fusion, which comprises the following steps of: firstly, acquiring ship target identification data and electronic reconnaissance identification data in a sequence remote sensing image; eliminating repeated data at the same moment; sequencing according to a time sequence, and calculating the azimuth angle of the ship at each moment; then, combining the electronic reconnaissance identification data and the ship target identification data meeting the time constraint, the space constraint and the ID constraint into associated data; and finally, performing trajectory fitting on the combined ship trajectory by using a weighted average method, and predicting the ship trajectory by using a linear equation to obtain a prediction result of the next-step trend of the ship. Compared with a traditional marine ship target analysis method, the method can
