Description of the Related Art As disclosed in Japanese Patent Publication No. 34-5099, a casing, a detection means which is built in the casing and detects the approach of a bombed object, and a bombardment object which is built in the casing and which is a detection means. Static torpedoes with explosives that explode on detection are known in the art. This torpedo catches the sound emitted by the bombed object by an omnidirectional sound wave receiver and explodes when the sound reaches a certain level or higher. In the torpedo disclosed in Japanese Patent Publication No. 34-5099, the casing has a substantially cylindrical shape and is in contact with the bottom of the water in a horizontal state, and a sound wave receiver is provided at one end of the casing. In order to prevent the sound wave receiver from getting in the way, a recess is provided at one end of the casing, and the sound wave receiver and its supporting member are held in the recess by the melting piece, and after the torpedo is dropped, The melting piece is melted, and along with this, the sound wave receiver and its supporting member come out of the recess, and the sound wave receiver is held horizontally. Since the static torpedo with such a structure not only has a very complicated structure but also has a small receiving area of the acoustic wave receiver,
There is also a problem that the sensitivity to receiving waves in the direct upward direction is also poor, and it explodes at a target ship or minesweeper that sails far away from this torpedo and makes no damage to the target ship. there were.

Then, a method for discriminating whether the sound wave is from directly above or from an oblique direction is described. However, in this method, since the sound wave receiver itself is omnidirectional, if the sound wave propagation path from the sound source is not the only direct path, in other words, the shallow sea water that is easily affected by the reflected wave of the sound wave from the seabed or the like. However, there is a problem that a malfunction is likely to occur due to the reflected wave when installed in. Moreover, in this method, a plurality of wave receivers must be installed at predetermined intervals, a plurality of signal processing circuits are required for the plurality of wave receivers, and a time difference detection circuit is also required. ,
There was also the problem of a complicated and expensive structure.
