<p>PURPOSE:To improve the capability of shooting down targets by providing means to output beam width control signal which sets the beam width that is required at minimum according to the relative distance and the change in target only when the lock-off signal is inputted from the relative distance signal and target change signal and providing means to control the antenna beam width by the beam width control signal. CONSTITUTION:A control device M' controls the attitude angle and flight route of the control device M' so as to keep a target 1 all the time within the beam scanning range of an antenna 7 and within the ranges of transmission and reception of a dome. At the same time the antenna beam width is controlled according to the relative distance from the target and target change even if lock-off is made, and the lock-off is controlled so as to be able to lock again a short time. It is, therefore, possible to prevent lock-off for the target 1, and even if it is locked off, it is possible to lock again in a short time so that a sudden fall in the capability of shooting down targets is prevented.</p> |
