However, because conventional anti-ship guided missiles did not have anti-missile missile countermeasures, they were shot down by anti-missile missile attacks from target ships before reaching target 1, and could not reach target 1. The drawback was that it hindered the ability to destroy targets. Particularly in recent years, there has been a strong trend to improve the performance of ship-based fire control systems and to equip various types of anti-missile missiles that operate in conjunction with these fire control systems as countermeasures against anti-ship guided missiles, making the above drawbacks an important issue. There is.

This invention was made for the purpose of improving such drawbacks, and is aimed at reducing the number of targets at the end of the guidance of anti-ship missiles.
launches an anti-missile missile, and when the meeting time of the anti-missile missile and the anti-ship guided missile is within a predetermined time, the carrier fire control system is activated by dispersing chaff and performing a predetermined evasive maneuver for a predetermined time. Anti-ship guided missile M, which neutralizes the device's ability to capture and track anti-ship guided missiles, reduces the attack ability of anti-missile missiles, increases the ability to penetrate target air defense networks, increases the probability of reaching the target, and improves target destruction ability. This is a proposal.

In addition, since the chaff functions as a soft kill against the target 1 and anti-missile missiles, it is also useful for defending the launcher 12.

In the anti-ship guided missile M configured as described above, when the anti-missile missile approaches the target 1 and an anti-missile missile is launched from the target 1, the launched anti-missile missile is detected via the high-speed target detection circuit 19. Then, it outputs a high-speed target signal, calculates the meeting time with the anti-missile missile from the signal via the operation period setting circuit 20, and when the meeting time is within the predetermined meeting time, the AND circuit 21 and the chaff dispersion control device 22 At the same time, the chaff dispersion control mechanism 23 operates to disperse chaffs, and at the same time, the anti-ship guided missile M is activated by the bias signal generation circuit 25 by the avoidance error signal from the constant circuit motion control signal generation section 24. During this period, the aircraft will change its conventional flight path and perform evasive maneuvers against anti-missile missiles. This also becomes an exercise in deception against Goal 1.

In addition, since the CHIAF functions as a soft kill against the target and protects the launcher, it can also be expected to have the effect of improving the probability of survival of the launcher.

Note that if a flare is used instead of a chaff, it is effective against infrared missiles, and by having both a chaff and a flare, it can be made effective against both radio wave missiles and infrared missiles.
