Claims (1)

[Scope of utility model registration request] In an active sonobuoy in which the set depth of the transducer can be changed by a remote command, the suspension cable installed in the probe part is stored, which floats on the sea during operational deployment and suspends the transducer at the set depth with a suspension cable. A sensor is arranged near the extending end of the hanging cable of the cable pack and outputs a detection signal when sensing, and a sensor is arranged at a position on the hanging cable that faces the sensor when the transducer is suspended to a set depth. at least one sensor sensitive body that makes the sensor sensitive when facing each other, and a signal generation circuit that generates a depth switching end signal indicating that the transducer has been switched to the set depth at the same frequency as the transmission frequency of the active sonobuoy; a gate circuit that receives a detection signal output from the sensor and gates the depth switching end signal generated by the signal generating circuit to output the depth switching end signal; A sonobuoy receiving circuit that receives, processes and outputs a depth switching end signal, and a sonobuoy transmitting circuit that outputs the output of the sonobuoy receiving circuit including the depth switching end signal as radio waves in a predetermined format. Active sonobuoy with depth switching end monitor function.
