Marine positioning enhancement method and system based on radar, and electronic equipment

The invention relates to the technical field of maritime positioning enhancement scheme design based on radars, and provides a maritime positioning enhancement method and system based on the radars, and electronic equipment, and the method comprises the steps: obtaining radar detection data of our ship and a target ship through an AIS system, the distance between the our ship and the target ship is calculated according to radar detection data; whether the distance between the our ship and the target ship is smaller than or equal to a first preset threshold value or not is judged; judging whether first positioning data of the our ship and the target ship are called through an AIS system or not according to a judgment result, and calculating second positioning data of the our ship according to the first positioning data of the target ship and the radar detection data; and carrying out positioning information fusion on the first positioning data and the second positioning data of the our ship to obtain third pos
