[Problems to be Solved by the Invention] Since the conventional guided aircraft are guided as described above, the guided flying body launched toward the target aircraft to be hit is the guided flight launched from the target aircraft. There was a problem that the target body was hit by the shogun and could not hit the target aircraft.

The present invention has been made to solve the above-mentioned problems, in which a guided aircraft launched toward a target aircraft to be hit is a guided aircraft launched from the target aircraft. The purpose is to hit the target aircraft without being hit, and also to obtain a guided aircraft suitable for this system.

[0006]

[Means for Solving the Problems] In the guiding method of the guide vehicle according to the first embodiment of the present invention, the guide vehicle launched toward the target aircraft is caused to fly at random without letting it fly straight. In this case, a random signal is generated by the guided flying object itself, and the guided flying object is caused to fly randomly for a predetermined period.

The guiding method of the guided vehicle according to the second embodiment of the present invention is a method in which the guided flying vehicle fired toward the target aircraft is made to fly randomly without flying straight. A random signal is generated by the command signal from the ground radar to randomly fly the guided vehicle.

[0008]

According to the first and second embodiments of the present invention, the guided flying body generates random acceleration and flies at random. The guided flying body that requires the above-mentioned guided flying body requires acceleration several times higher than that of the guided flying body that randomly flies. I can't kill you.

【Example】

Example 1. Embodiment 1 of the present invention will be described below with reference to the drawings. FIG. 1 is a diagram showing a method for guiding a guided vehicle according to the present invention. In the figure, 1 is a target aircraft to be hit,
Reference numeral 2 is a ground-based radar system, which comprises a radar 3 for searching a target aircraft and a launcher 4 for launching a guided vehicle. Reference numeral 5 is a guided flying object that is launched from the launcher 4 and is required to hit the target aircraft 1. On the other hand, 6
Is a guided flying object launched from the target aircraft 1 in order to hit the guided flying object 5. A is an expected meeting point between the target aircraft 1 and the guided vehicle 5.

Next, the operation will be described. The radar 3 searches for the target aircraft 1 to be hit and obtains information such as the distance and azimuth angle of the target aircraft. Based on the information obtained above, the timing for firing the guide vehicle 5 is calculated, and a firing signal for firing the guide vehicle 5 is generated and transmitted to the launcher 4. The normal launch timing is generated when the target aircraft 1 enters within the predetermined maximum range of the guided flying vehicle 5. The launcher 4 receives the launch signal from the radar 3 and, at the same time, launches the guided vehicle 5. Immediately after launching, the guided vehicle 5 flies straight toward the expected meeting point A between the target aircraft 1 and the guided vehicle 5, but a predetermined period is random depending on the holding function of the guided vehicle described later. Let's fly. The random flight period is from a few seconds after the launch to a few seconds before the target aircraft 1 and the guided flying vehicle 5 meet, and is not particularly specified. Immediately after launch, the guided vehicle is unstable, and before hitting the target aircraft 1, it is necessary to steer toward the target aircraft. Random flight should not be performed immediately after launch and immediately before the impact.

On the other hand, the target aircraft 1 has the same function as the radar 3.
It possesses a radar having the performance, detects the guide flying body 5 emitted by the radar, and fires the guide flying body 6 to hit the guide flying body 5. The guided flying body 6 flies toward the expected meeting point between the guided flying body 6 and the guided flying body 5, but since the guided flying body 6 randomly flies, The guided flight 5 cannot be hit. In other words, in order to kill a randomly flying guided vehicle,
It is necessary to have an induction vehicle that has an acceleration capacity that is several times that of a randomly flying vehicle. For example, 60G is required to shoot an induction vehicle that has an acceleration capacity of 20G.
The above-mentioned guided aircraft with acceleration ability are required, and it is not possible to realize a guided aircraft having the above-mentioned ability.

Reference numeral 9 is an autopilot, which generates a steering signal for controlling the guidance vehicle toward the expected meeting point of the target aircraft based on the signal obtained by the guidance control device. Reference numeral 10 denotes a wing servo actuator, which steers the wing in response to a steering signal obtained by the autopilot. A random flight control device 11 is composed of a random signal start circuit 12, a random signal stop circuit 13, and a random signal generator 14. The random signal start circuit is a circuit for starting the random signal generator 14 described later after the guided flying object leaves the launcher and a predetermined time has elapsed, and the random signal stop circuit is for the guided flying object to be the target aircraft. Is a circuit that stops the random signal generator 14 when the time required to strike is within a predetermined time. The timing for starting and stopping the random signal differs depending on the characteristics of the guided vehicle and is not specified. Reference numeral 14 is a random signal generator, which generates a random signal for randomly flying the guided flying object, and the start and stop control of the random signal generation is performed by the random signal start circuit 12 and the random signal stop circuit 13 described above. Done. Random signal generator 14
