    • A device is described for the transmission and reception of acoustic signals, particularly for submarine exploration, comprising a group of electroacoustic transducers (17) arranged around a reception electroacoustic transducer (18). All transducers are of a paraboloidal reflector type and are arranged with their axes parallel to each other and having their openings on the same plane orthogonal to these axes. Each of the transmission transducers has a pair of electrodes (30), disposed near the focus, connected to an electrostatic energy supplier (3), in order to simultaneously receive from it a predetermined energy amount, which is different for each transducer, so as to generate an electric discharge and, consequently, an acoustic pulse. The reception transducer has a piezoelectric detector near its focus which is connected to circuits and devices (5) for processing the received signals.
    • 描述了用于发送和接收声信号,特别是用于海底探测的装置,其包括布置在接收电声换能器(18)周围的一组电声换能器(17)。 所有传感器都是抛物面反射器类型,并且它们的轴线彼此平行并且在与这些轴线正交的同一平面上具有开口。 每个传输换能器具有设置在聚焦附近的一对电极(30),其连接到静电能供应器(3),以便同时从其接收与每个换能器不同的预定能量,以便 以产生放电,从而产生声脉冲。 接收传感器在其焦点附近具有压电检测器,其连接到用于处理接收信号的电路和设备(5)。
