The acquisition display screen is a screen that indicates that the helicopter on board has been acquired by the acquisition laser from the launcher.
Specifically, as shown in FIG. 9, the controller 64 determines whether or not the capture identification of the received light data matches the capture identification stored in the control unit 64 of the controller 60 when the avoidance device receives the capture laser. If they match, "capture" is displayed for a certain period of time (for example, twice the capture laser transmission interval). The display of "catch" is made by changing FIG. 9(a) to FIG. 9(b). In this case, the background color is changed to produce sound.
After that, when the helicopter is out of the sighting range of the launching side due to evasive action and the acquisition laser is not received, the "acquisition" display is erased.

In this case, after implementing a tracking jamming measure corresponding to the identification of the guided bullet contained in the received tracking laser (implementation of the effective avoidance device shown in Fig. 8), the evasion will be successful by detecting acceleration above the specified value. judge.

In this way, "successful avoidance" is displayed as the determination of avoidance success, and even if a tracking laser and a landing laser with the same transmission number are received after that, they are ignored.
However, if the incoming laser is received before the determination of avoidance success is made, it is determined that the avoidance has failed, and "avoidance failure" is displayed.

If it is determined that the target has been determined (Yes), automatic tracking is started (S14). Then, when the target is acquired (S15), the launcher transmits the acquisition laser to the evasion device for a specific time (first specific time).
The avoidance device receives the catching laser and causes the operation display 50 to display the catching indication when the catching identification set for training matches (S22).

After transmitting the acquisition laser for the first specific time, the launcher transmits the tracking laser for the second specific time (guidance time) as processing for launching the guided bullet (S16).
When the avoidance device receives the tracking laser from the launcher, it performs tracking display (S23). Subsequently, the avoidance device determines whether or not the tracking laser has not been received (S24), and if it has not been received (Yes), the avoidance success is displayed (S28), and the process ends. do.

If the tracking laser is not unreceived (No), it is determined whether or not a workaround (tracking interference measure) has been entered (S25). return. If a workaround is input (Yes), it is determined whether a sharp turn is detected by the sensor unit 65 (S26), and if a sharp turn is detected (Yes), the process proceeds to S28.

When the guidance time elapses, the launcher transmits the landing laser to the avoidance device (S17), and terminates the process.
If the avoidance device does not detect a sharp turn in the sharp turn detection process (S26) (No), then it determines whether or not it has received a landing laser (S27). If the landing laser has not been received (in the case of No), the process returns to determination processing S24. If a laser beam has been received (if Yes), an evasion failure is displayed (S29), and the process ends.
