The sonar sensor signal may include a sonar sensor signal for ambient noise near the target (direction, distance designation, etc.).

While the engagement status is changed from "Firing" -> "Finished", if it rises above the threshold by observing the change in the sonar sensor signal of the noise around the target, it is judged as "Probable to hit" ", the multi-function console 224 may display the determination result in text at the upper right corner of the sonar sensor signal.

In addition, the multi-function console 224 displays the predicted hit evaluation information received from the sonar hit evaluation device (225).

The sonar hit evaluation device 225 may determine whether the engagement status of the armed is being fired based on the engagement status information received from the tactical information processing device 222 . The firing preparation and firing status information of the armed 200 can be checked through the engagement status message sent from the engagement module in the tactical information processing device 222 . At this time, the engagement status message is periodically transmitted from the engagement module in the tactical information processing device 222 , and the sonar hit evaluation device 225 periodically receives the message to determine the engagement status of the armed forces being assigned. There is an engagement module in the tactical information processing device 222 .

If the target instruction command is not transmitted to the arming 200 , the sonar hit evaluation device 225 returns to step 301 .

However, when the target instruction command is transmitted to the arming 200, the sonar hit evaluation device 225 of the control center 220 in the ship monitors the assigned armed engagement state at a cycle of 1 second in step 303.

The sonar hit evaluation device 225 determines whether the armed engagement state is "ready to fire" state in step 305.

If the armed engagement state is not "ready to fire" state, the sonar hit evaluation device 225 returns to step 305 .

However, if the armed engagement state is "ready to fire" state, the sonar hit evaluation device 225 determines whether the target is detected by the sonar sensor 210 in step 307 .

When the armed launch preparation is completed, the sonar hit evaluation device 225 checks whether the resources of the sonar sensor 210 can be utilized. Whether the resource can be utilized can be checked using a status message sent from the sonar sensor interlocking unit 223 when there is an enemy target detected by the sonar sensor 210 .

If the target is detected by the sonar sensor 210, the sonar hit evaluation device 225 determines whether the armed engagement state is “in firing” in step 309 . If the armed engagement state is not "in firing", the sonar hit evaluation device 225 returns to step 309.

Simultaneously with the operation of step 313, the sonar hit evaluation device 225 of the control station 220 in the ship determines whether the rate of change of the peak value of the sonar sensor signal screen is greater than the set value (a) in step 315 .

If the change rate of the peak value of the sonar sensor signal screen is less than or equal to the set value (a), the sonar hit evaluation device 225 of the control station 220 in the ship determines that the hit failure is likely as the hit prediction result in step 317 .

When the change rate of the peak value of the sonar sensor signal screen is greater than the set value (a), the sonar hit evaluation device 225 of the control station 220 in the ship determines that the hit is likely as a hit prediction result in step 319 .

The sonar hit evaluation device 225 of the control station 220 in the ship receives the hit prediction results of steps 317 and 319, and determines whether the armed engagement state is “fired” in step 321. If the armed engagement state is not "fired", the sonar hit evaluation device 225 returns to step 315 .

However, when the armed engagement state is "fired", the multi-function console 224 of the control center 220 in the ship displays the hit prediction result in the upper right corner of the sonar sensor signal image in step 323.

The sonar hit evaluation device 225 of the control station 220 in the ship determines whether it is the result of the hit selected by the operator in step 325 . The operator decides whether to hit the target based on the information displayed in the sonar sensor signal, and processes “hit” or “miss” for the enemy target.

The sonar hit evaluation device 225 of the control station 220 in the ship is terminated when the hit result selected by the operator is “hit failure”. However, if the operator selects "hit" and processes it, the multi-function console 224 of the control station 220 in the ship turns off the sonar sensor signal screen in step 327, and the sonar hit evaluation device 225 of the control station 220 in the ship uses the newly acquired sonar sensor signal characteristics for the hit evaluation of the sonar hit evaluation device.

The sonar hit evaluation device 225 of the control station 220 in the ship updates the set value (a) by cumulatively averaging the newly acquired sonar sensor signal with the existing set value in step 329 . In case of hit processing, the threshold point is adjusted to the average value accumulated with the existing threshold point of the acquired sonar sensor signal.

The embodiment of the present invention can improve the accuracy and speed of the hit evaluation by automatically checking whether or not the target is hit through a sonar sensor after firing to an underwater target or when visibility is poor when evaluating an enemy's marine target after firing.

The embodiment of the present invention is effective in cost reduction because it checks the firing state of the armed forces and whether the resources of the sonar sensor are utilized by using the message in the combat system.

Those of ordinary skill in the art to which the present invention pertains to the above-described contents can be modified and modified without departing from the essential characteristics of the present invention.
