Finally, when it directly hits the target (11) or passes near the target (!), it detonates the second ammunition αe according to the detonation signal from the detonation signal generation circuit (Is) and damages the target (1). It works like this.

However, conventional anti-ship guided missiles did not have any countermeasures against shells, so they could be damaged by shell attacks from target ships.
It had the disadvantage that if it was shot down before reaching its target, it would not be able to reach its target, which would hinder its ability to destroy the target. In particular, in recent years there has been a strong tendency to improve the performance of ship-based fire control systems and to equip rapid-firing cannons that operate in conjunction with these fire control systems as countermeasures against anti-A guided missiles, making the above drawbacks an important issue. ing.

[Summary of the invention]

This invention was made for the purpose of improving such drawbacks, and when the target (dish) starts a shell attack at the end of the guidance of an anti-ship missile, it scatters chaff and performs a predetermined evasive movement for a predetermined period of time. By doing so, II! On-board fire control device vs. W
This proposal proposes an anti-ship guided missile that neutralizes the ability to capture and track L-guide missiles, reduces the ability to attack artillery, increases the ability to penetrate target air defense networks, increases the probability of reaching the target, and improves the target value i ability.

Note that Chaff is also useful for defending 2-launchers, as it acts as a soft kill against Target (11).

Constructed of the above. When the anti-Wi guided missile M approaches target +11 and receives a shell attack from target (11), the explosion sound of the shell is detected by the shell explosion sound detection circuit 4, and is set arbitrarily before launching the anti-ship guided missile. Then, when the meeting time with the target il+ reaches a predetermined time, the signal output from the operation period setting circuit meets the conditions of a high level (or low level) signal, the AND circuit can.

Through the chaff dispersion control device (2), the chaff pattern control system is activated to eliminate the chaff, and at the same time, a constant rotation movement control signal is issued to avoid the error signal. is applied to the steering device all via the bias signal generating circuit (c), so that the paired bomb M changes its conventional flight path for a predetermined period and performs a forceful movement with respect to the target (11). .However, if it is not attacked by artillery shells, the U.S. tracking function will be activated.

It has the effect of neutralizing the ability of the ship-based fire control system to capture and track anti-ship guided missiles, reducing the Nu power of artillery shell attacks, increasing the ability to penetrate target defenses and the probability of reaching the target, and improving the ability to destroy targets.

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