を停止した後でなければ使用することができない。FIG. 2 shows the relationship between the control signal and the transmission of acoustic data signals from a plurality of sonobuoy devices. As shown in FIG. 2, a plurality of sonobuoy devices A, B,..., E, F,.
When the control signal is transmitted, the plurality of sonobuoy devices each transmit the acoustic data signal to the own device only when the control signal is transmitted. By setting the transmission interval of the control signal to be longer than the time required for each sonobuoy device to transmit the acoustic data signal, it is possible to prevent interference between a plurality of sonobuoy devices. That is, a plurality of sonobuoy devices can be operated in a time sharing manner. Therefore,
Even if a plurality of sonobuoy devices use the same frequency carrier, all the sonobuoy devices can be identified. Incidentally, as shown in FIG. 3, the conventional sonobuoy device transmits the acoustic data signal independently of the control signal (irrespective of the presence or absence of the sonar transmission signal and the sonar reflection signal). The sonobuoy device E that uses a carrier wave having the same frequency as the above can only be used after the sonobuoy device A has stopped operating due to battery exhaustion.
