In order to improve the attack ability of terminal guided projectile on maritime over the horizon maneuvering target, it is necessary to quickly identify the turning maneuvering behavior of the target. Based on the image information obtained by UAV continuous observation of ships, the ship pixel width in the observation image is converted into the observation width of the ship vertically projected on the sea surface by the projection conversion method, and the rolling angle of the ship is calculated by the observation width. On this basis, a method to quickly judge the turning maneuver state of ships based on the change of ship roll is proposed. This method can be used to predict the turning rate, assist in selecting the turning maneuver model of fire control targets, and predict the future turning maneuver point of maritime maneuvering targets. However, this paper mainly studies the method of quickly judging target turning maneuver, and does not involve the research on the initial value prediction and filtering of target turning rate.
Key words: observation width; roll; turn maneuver state
