METHOD FOR CHASING TARGET USING DOUBLE GATE

摘要

The present invention relates to a method for chasing a target using a double gate which draws a sub-tracking gate to have a greater radius than a main tracking gate, sets a size in proportion to a speed resulting value of a previous target, and is set by a direction close to a predicted position of the target. A ship having turning or change in speed frequently causes target lost phenomena. The target lost phenomena of the ship having turning or change in speed can be prevented by a double gate tracking algorithm in which the sub-tracking gate is added.
