Description

TECHNICAL FIELD The present invention relates to a guidance control method for a parent-child guidance flying vehicle including a large number of sub-munitions having a guidance control device.

[Prior Art] FIGS. 3 and 4 are views showing a state in which a conventional parent-child guided flying vehicle searches for and tracks a target. In FIG.
(2) is a master bullet seeker, (3) is a transmitter mounted in the above-mentioned master bullet (1), (7) is a subsidiary bullet, (8) is a subsidiary bullet seeker,
(9) is a guidance control device for the sub-bullet (7), (10) is a parachute mounted at the rear of the sub-bullet (7), (11) is a target, and (14) is an electromagnetic wave radiated from the target. .

Next, the operation will be described. In Fig. 3, the target (1
The parent bullet (1) flying toward 1) emits a submunition (7) when approaching the target (11) to a predetermined position by inertial guidance or active radar homing.

In Fig. 4, when the ejected submunition (7) falls to a predetermined altitude, the parachute (10) is unfolded, the falling speed is slowed down, and the target (11) is searched by the submunition seeker (9). The electromagnetic wave (14) radiated from the target (11) is received, and the target (11) is captured and tracked by the guidance control device (9).

[Problems to be solved by the invention]

Since the conventional method for searching and tracking a parent-child guided air vehicle is configured as described above, in the case of having a large number of sub-bullets, each sub-bullet is equipped with a transmitter and active radar homing It is difficult to realize the guidance because the size of the sub-bullet is drastically increased and it is costly, and it is limited to the passing-homing guidance method that passively receives the electromagnetic wave radiated from the target. And
The range was short, and there were problems such as the ability to capture and track in rainy weather.

The present invention has been made to solve the above-mentioned problems, and obtains a semi-active homing guidance system having a long range and all-weather characteristics that cannot be obtained by the passive homing guidance system as a guidance control method for sub-resilience. The purpose is to

[Means for solving problems]

A parent-child guided vehicle guidance control method according to the present invention is equipped with a transmitter in a parent bullet, delays the relative drop velocity of the parent bullet after the child bullet is ejected, and aims the parent bullet as an irradiator of a subsidiary bullet seeker. It is designed to be positioned behind the sub-bullet.

[Work]

The guide control method according to the present invention allows the master bullet after the slave bullet is ejected to fall at a slow relative velocity with respect to the target bullet so that the master bullet is always arranged behind the slave bullet with respect to the target. Radio waves are radiated from the target to the target, and the reflected waves from the target are captured and tracked by the sub-shot.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings. First
In FIG. 2 and FIG. 2, (1) is a master bullet, (2) is a master bullet seeker, (3) is a transmitter mounted in the above master bullet (1),
(4) is the parachute attached to the parent bullet (1),
(5) is the parasit storage, (6) is the propulsion unit,
(7) is a sub-bullet, (8) is a sub-bullet seeker, (9) is a guidance control device for the above-mentioned sub-bullet (7), (11) is a target, (12) is a radio wave radiated toward the target, ( 13) shows the reflected wave from the target.

Next, the operation will be described. In Fig. 1, the target (1
When the parent bullet (1) flying toward 1) reaches a predetermined position above the target (11) by inertial guidance or active homing guidance, it ejects a submunition (7).

In Fig. 2, the parent bullet (1) that emitted the sub-bullet (7) is
The propulsion unit (6) is separated, the parasite (4) stored in the parasite storage unit (5) is unfolded, and the parasite (4) falls at a slower speed than the submunition (7). The parent bullet (1) placed above the sub-bullet (7) is targeted (11) by the transmitter (3).
The radio wave (12) continues to be radiated toward the target, and the main bullet (1) itself tracks the target (11) by active homing, and the slave bullet Seeker (8) also reflects (1) from the target (11).
3) is received and the target (11) is captured and tracked by the guidance control device (9).

As described above, according to the present invention, the active homing is performed by the master bullet seeker, the transmitter is used as the slave bullet illuminator by the master bullet seeker when active homing, and the master bullet seeker is a child. Since the active homing is performed on the target even after it becomes an irradiator for bullets, the feature is that the radio wave irradiation to the target is not missed.

〔The invention's effect〕

As described above, according to the present invention, the transmitter is provided in the master bullet so that the master bullet can continue to irradiate the target from behind the slave bullet after the slave bullet is ejected. It is possible to control it, and it has the effects of achieving long range and weather resistance.
