Next, the operation / action will be described. In FIG. 6, when the master bullet (1) flying toward the target (11) reaches a predetermined position, it deploys the deployment shell (10) and drops the slave bullet (9). In FIG. 7, when the sub-bullet (9) falling toward the target drops to a predetermined position, the parachute (35) mounted on the rear part is deployed, and the target (11)
The slave antenna (16) receives the electromagnetic wave (36) radiated from the target and tracks the target (11).

[Problems to be solved by the invention]

Since the conventional parent-child guided air vehicle is configured as described above, the sub-bullet must search for the target again by the passive method that receives the electromagnetic waves radiated from the target after being emitted from the parent bullet. However, because the range is short and the falling speed is significantly reduced by adding parasit, there is a high possibility that the target will be detected and attacked in reverse. Also, even if a large number of submunitions were used, they could attack the same target.

The present invention has been made to solve the above problems, and an object of the present invention is to obtain a device that extends the range of sub-munitions and improves the quick-attacking ability and target identifying ability of sub-munitions.

[Means for solving problems]

The parent-child guided air vehicle according to the present invention has a parent bullet, an antenna,
It has a transmitter, a receiver, a signal processing device, and a steering control device for tracking the target by the target information obtained by these, a steering wing, and it can be separated so that the target information obtained by the master ammunition can be transmitted. The sub-munitions are connected by a connector, and at the same time, the sub-munition grasping device can be expanded outside the main bullet and can also serve as a launch launcher for the sub-munition. The sub-munition has an antenna, a receiver, a signal processor, a steering controller, a deployable steering wing, and a rocket motor, and receives reflected waves from the target to track and attack the target at high speed. Is.

[Action]

The parent-child guided flying vehicle according to the present invention transmits target information obtained by the parent bullet to the child bullet before firing the child bullet, and each child bullet is fired after selecting and capturing a different target. In addition, a rocket motor is added to the sub-shot, and after launching the sub-shot, the main shot continues to illuminate the target while tracking the target from behind the sub-shot and the sub-shot receives the reflected wave from the target. Capture and track each goal.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings. First
4 to 4, (1) is a main bullet, (2) is an antenna, (3) is a guidance control device including a transmitter, a receiver and a signal processing device, (4) is a radio altimeter, (5) Is a steering controller, (6) is a steering wing, (7) is a tail, (8) is a new launch launcher, (9) is a submunition, and (10) is a new part for accommodating the submunition (9). Shell deployment shell, (11) target, (12) transmitted wave radiated from the main antenna (2) toward the target (11), (13) reflected wave from the target (11), (14) Is a connector for fixing the sub-bullet (9) to the main bullet (1) in a signal transferable state, (15) is a sub-bullet deploying wing, (16) is a sub-bullet antenna, (17) is a receiver, (18) ) Is a signal processing device, (19) is a sub-lens steering control device, and (20) is a sub-lens rocket motor.

Next, the operation / action will be described. In FIG. 1, when the master bullet (1) fired from the launching launcher (8) drives the steering wing (6) to fly over the target, the antenna (2) emits radio waves (12) to irradiate the target ( At the same time as searching for 11), the deployment shell (10) is deployed to expose the sub-bullet (9). When the sub-bullet (9) decides each target by the information from the parent bullet, the rocket motor (20) is ignited,
Dive to each goal (11). The main bullet (1) is
While radiating radio waves from the antenna (2) to the entire target group,
It slowly descends from above the sub-bullet (9) toward the center of the target group. The slave bullet (9) receives the reflected wave (13) from the target of the parent bullet transmission wave (12) and tracks each target (11).

Next, a detailed structure of the sub-bullet storage and deployment mechanism and the sub-bullet will be described. FIG. 2 is a sectional view of FIG. 1 taken along the line AA, and FIG. 3 is a deployment shell (10) of the parent bullet in FIG.
Indicates that the sub-bullet (9) is confronting the target. FIG. 4 is an enlarged view of the sub-unit storage portion of FIG. 1 showing the details of the sub-unit.

Next, a detailed description will be given of the actions of the parent and sub-munitions from the search for the target to the tracking. In FIG. 5, (21) to (34) show the actions / actions at each stage of the parent bullet and the submunition. At step (21), when the master bullet (1) flying over the target reaches the predetermined altitude by the radio altimeter (4), at step (22), the transmitter of the guidance controller (3) is sent. Radio waves (12) are transmitted to drive the antenna (2) to search for the target (11). When it is confirmed that the guidance control device (3) has captured the target (11) in step (23), a shell deployment command is given and the deployment shell (10) deploys (step (24)). At the same time, target position information is given to the sub-bullet (9) through the connector (14), and the sub-bullet antenna (16) starts searching for the target (step (25)). The signal processing device of the master bullet guidance control device (3) identifies the target to be attacked by each slave bullet (9) (step (28)),
The target information is transmitted to each sub-bullet (9), and the sub-bullet (9) searches for and captures the target in steps (25) to (27) until each sub-bullet (9) captures the selected target. Repeat selection. Target the target (11) specified by the main bullet (1) with the sub-bullet (9)
When is captured, the target capture completion signal is transmitted from the sub-bullet (9) to the parent bullet (1), and the parent bullet (1) confirms the firing of the sub-bullet of step (29). Therefore, a sub-projectile firing command is given to the sub-bullet (9), and the sub-lens rocket motor (20) is ignited in step (30). A little later than the step (29), the connector is disconnected at the step (31), and the sub-bullet (9)
Is fired. After launching the sub-bullet, the deploying wing (15) is deployed (step (32)), and the antenna (16) receives the reflected wave (13) from the target of the transmitted wave (12) of the parent bullet, and the target tracking is performed. Run. On the other hand, when it is confirmed at the step (33) that the firing of the sub-bullet (9) is completed, the deployment shell (10) that has fired the sub-bullet is closed (step (34)).

〔The invention's effect〕

As described above, according to the present invention, since the target search / tracking method for sub-resets is a semi-active method in which the main-ball transmitter is used as an irradiator, a long range is realized and the main-balls Since a rocket motor is added to the sub-shot as a means to position it behind the bullet, the sub-shot has added quickness, and since each sub-shot is fired after capturing a different target, the target identification ability is improved. There is an effect such as.
