PROBLEM TO BE SOLVED: To measure underwater information such as an underwater electric field generated from an underwater vehicle or the like by an apparatus which can be dropped from an aircraft or the like, which is simple, and which is less susceptible to oscillation of a tidal current or the like.SOLUTION: An underwater information measuring apparatus comprises: a buoyant body 3 provided with a GPS reception antenna 1 receiving GPS information, a GPS receiver 4 determining a GPS position from information obtained from the GPS reception antenna, a transmitter 5, and a transmission antenna 2 transmitting information from the transmitter 5; a spherical shell 9 provided with three pairs of electrodes 10-1 to 10-6 for detecting an underwater electric field and connected to the buoyant body 3 by a first cable 8; and a processor 13 detecting a potential difference from potentials obtained from the electrodes. The transmitter 5 transmits the GPS position information from the GPS receiver 4 and output information from the processor 13 from the transmission antenna. The spherical shell 9 expands from a contraction state when landing in water and supports the respective paired electrodes to be apart from one another.SELECTED DRAWING: Figure 1
【課題】水中航走体等から発生する水中電界等の水中情報を航空機等から投下可能かつ簡易かつ潮流等の動揺を受けにくい装置により計測する。【解決手段】GPS情報を受信するGPS受信アンテナ1、これから得た情報からGPS位置を求めるGPS受信機4、送信機5、送信機5からの情報を送信する送信アンテナ2が設けられた浮力体3と、水中電界を検出するための三対の電極10−1〜10−6が設けられていて、浮力体3と第1の索8で繋がれた球殻9と、前記電極から得た電位から電位差を検出する処理器13とを備える。送信機5はGPS受信機4からのGPS位置情報及び処理器13の出力情報を送信アンテナから送信する。球殻9は着水時に縮小状態から膨張して、各対の電極同士を離間状態に支持する。【選択図】図1
