However, when the target (1) was simultaneous multiple targets, the priority of target selection was determined based on the signal strength or speed of the multiple targets, and therefore the target defense point is not always suitable. It was not possible to select a target to go and guide it toward that target (1), and the probability of destroying the own defense point was high.

Particularly in recent years, there is a strong demand for improvement in simultaneous multi-target handling performance, and among them, it is an important issue to overcome the above-mentioned blunders by improving the identification of the threat level.

In this invention, the priority of the defense points is stored in the flying body before the flight, and the target (the degree of threat of The aim is to obtain a flying object that improves simultaneous multi-target coping performance capability and dramatically improves self-defense capability by guiding and shooting down at high target).

[Means for Solving the Problems]

The flying object according to the present invention is a means for detecting a target flight direction and outputting a target flight direction signal from a target signal and an attitude angle signal from an inertial device section (9), and a target signal and inertial device section. Means for detecting the target flight altitude and outputting the target flight altitude signal from the altitude signal from (9), and means for predicting and calculating the target impact point by the target flight direction signal and the target flight altitude signal And remember the priority of the defense point in advance before flying,
The target (1) is determined by means for determining the priority of defense points near the target at the time of capturing the target and outputting a defense point priority signal, and the error signal from the output of the above-mentioned means and the above-mentioned means and the signal processing unit (10). The target with a high degree of threat by determining the threat level of the target (a target that goes toward a defense point with a high priority of defense points)
And means for outputting an induction signal for inducing the induction.

[Action]

This invention pre-stores the priority of defense points in the flying body M in advance, and when the player engages with multiple targets at the same time, the goal (threat) toward the defense point with the highest priority of defense points is set. The flying body M is controlled so that it can be guided down to a high target and can be shot down.

The flight altitude detection circuit (20) is the target flight direction signal output from the target flight direction detection circuit (18) and the target flight altitude signal output from the target flight altitude detection circuit (19). The target impact point prediction calculation unit (21) stores the defense points in advance in order of priority before flying, and determines the priority of defense points near the target when engaging with multiple simultaneous targets. Defense point Outputs a priority signal The priority ranking determination memory unit (22) is the target bullet impact point calculated by the target bullet impact point prediction calculation unit (20) and the defense point priority signal and signal processing of the output of the defense point priority ranking determination memory unit (21).

In the flying body M configured as described above, the attitude angle and the flying path of the flying body M are controlled so as to guide them toward the target with high threat at the time of simultaneous multiple targets, and at the same time, from each device The signal as shown in FIG. 2 is output.
Also, as shown in Fig. 3 (a), with conventional flying objects. In the case of engaging with multiple targets at the same time, a target with a high signal strength or a high speed was guided and shot down, whereas in the present invention, as shown in FIG. Because the rank is stored in the flying body M, and when the player engages in multiple simultaneous targets, he is guided to a target (a target with a high degree of threat) heading toward a defense point with a high priority of defense points, and shoots down. Simultaneous multi-target responsiveness will be improved and self-defense capability will be improved.
