Hereinafter, embodiments will be described with reference to the drawings. The same parts in the drawings are designated by the same number, detailed description thereof will be omitted as appropriate, and different parts will be described. The drawings are schematic or conceptual, and the relationship between the thickness and width of each part, the ratio of the sizes between the parts, and the like are not necessarily the same as the actual ones. Further, even when the same parts are represented, the dimensions and ratios may be different from each other depending on the drawings.

FIG. 1 is a schematic diagram showing a flying body guidance system according to the embodiment. The flying body guidance system includes, for example, a first flying body 10 and a second flying body 20.

The first flying object 10 and the second flying object 20 are launched from the ground after the target flying object 30 is detected by, for example, a radar site on the ground and the detection information is received.

The first flying object 10 is located at a first altitude higher than the altitude of the target flying object 30. The first flying object 10 emits, for example, a radar wave RW1 to the target flying object 30, and detects the reflected wave to detect the position, altitude, flight direction, and flight speed of the target flying object 30. The flight data such as the above is detected and transmitted to the second projectile 20 by the radio wave MW.

The second flying object 20 is located at a second altitude lower than the first altitude of the first flying object 10. The second flying object 20 receives the flight data of the target flying object 30 transmitted from the first flying object 10, and flies toward the target flying object based on the flight data. The second altitude is, for example, substantially the same as the altitude of the target flying object 30.

The first flying body 10 flies while tracking the target flying body 30, for example, the target flying body 20 is in contact with the target flying body 20 until the second flying body 20 meets the target flying body 30. 30 flight data are transmitted sequentially. Here, the "meeting" means that the second flying object 20 reaches a position close to the target flying object 30. For example, when the second flying object 20 is provided with a detection device, the detection device includes reaching a position where the target flying object 30 can be captured.

For example, each time the second flight body 20 receives flight data of the target flight body 30 from the first flight body 10, the second flight body 20 flies toward the target flight body 30 while modifying the flight course. For example, the second flying object 20 flies while maintaining a second altitude that is substantially the same as the altitude of the target flying object 30. When the altitude of the target flying object 30 changes, the altitude of the second flying object also changes accordingly.

For example, the RCS for the radar wave radiated to the target projectile 30 from below or horizontally may be small, and the RCS for the radar wave radiated from above may be relatively large. In such a case, it is advantageous to irradiate the radar wave from the first flying object 10 located at a higher altitude than the target flying object 30 and detect the flight data of the target flying object 30.

2 (a) and 2 (b) are schematic views showing a method of launching a flying body according to an embodiment. FIG. 2A is a schematic view showing the process leading to the launch of the first flying body 10 and the second flying body 20. FIG. 2B is a schematic diagram showing a process of arranging the first flying object 10 at the first altitude and arranging the second flying object 20 at the second altitude.

As shown in FIG. 2A, when the radar site 40 deployed on the ground irradiates the radar wave RW2 and detects the target flying object 30, the first flying object 10 and the second flying object 20 Detection information such as flight data of the target projectile 30 is transmitted to the launch site 50. At the launch site 50 that has received the detection information of the target flight body 30, the first flight body 10 and the second flight body 20 are launched based on the detection information of the target flight body 30.

For example, the target projectile 30 may be detected at a plurality of radar sites 40, and the flight data of the target projectile 30 may be acquired based on the data transmitted from each radar site 40. As a result, it is possible to cope with the case where the RCS of the target flying object 30 is small.

As shown in FIG. 2B, the first flight body 10 and the second flight body 20 fly in a united state until they reach the third altitude, and are separated at the third altitude, for example. The first flying object 10 is separated from the second flying object 20 at the third altitude, and then rises to the first altitude higher than the altitude of the target flying object 30. The second flying object 20 is located at, for example, a second altitude that is substantially the same as the altitude of the target flying object 30. The third altitude may be, for example, substantially the same as the second altitude, or may be an altitude lower than the second altitude. Further, the third altitude is higher than the second altitude, and the second projectile may descend to the second altitude.

After that, as shown in FIG. 1, the first flying object 10 irradiates the radar wave RW1 from above the target flying object 30, detects the reflected wave, and acquires the flight data of the target flying object 30. .. The first flying body 10 transmits the flight data of the target flying body 30 to the second flying body 20 and guides the second flying body 20 to meet with the target flying body 30.

The embodiment is not limited to the above example, and for example, the first flying object 10 and the second flying object 20 may be launched separately and arranged at the first altitude and the second altitude. .. When the first flying body 10 and the second flying body 20 are launched separately, they are arranged in different launch devices. Further, the first flying body 10 and the second flying body 20 may be launched at the same time, or the second flying body 20 may be launched after the first flying body 10 is launched.

The second flying body 20 preferably flies at a higher speed than the first flying body 10. Therefore, it is preferable that the second projectile is provided with a propulsion device having a higher output. However, when the first flying body 10 and the second flying body 20 are combined and launched, the weight of the second flying body 20 is limited, and the second flying body is equipped with a high-power propulsion device. Can be difficult. On the other hand, when the first flying body 10 and the second flying body 20 are launched separately, there is an advantage that a configuration according to each purpose can be adopted.

The flight control unit 15 controls the propulsion unit 17 so as to track the target flight body 30, for example, based on the flight data of the target flight body 30. The propulsion unit 17 includes, for example, a jet engine and flies the first projectile 10.

As shown in FIG. 3B, the second flying body 20 includes a transport unit 21, a communication unit 23, a flight control unit 25, and a propulsion unit 27.

The transport unit 21 holds the load until it meets the target projectile 30. The communication unit 23 includes, for example, a transmitter / receiver for wireless communication with the communication unit 13 of the first flying object 10. The communication unit 23 is configured to receive the flight data of the target flying object 30 transmitted from the first flying object 10 and transmit the flight data of the second flying object 20 to the first flying object 10. May be done.

For example, when the first flying body 10 confirms that the second flying body 20 has met with the target flying body 30, the tracking of the target flying body 30 is completed and the landing is performed at a preset point. It is composed of.

The flight control unit 25 controls the propulsion unit 27 based on, for example, the flight data of the target flight body 30 transmitted from the first flight body 10. The flight control unit 25, for example, flies the second flight body 20 toward the meeting point with the target flight body 30 by linear optimum navigation. The propulsion unit 27 includes, for example, a jet engine.
