    • A passive sonar system which forms multiple receiver beams for detection of possible targets. The transducer array for the system includes a plurality of pairs of transducers, the transducers of each pair lying along a generally radial line emanating from a central point. The output signal from the outer transducer of each pair is delayed by 90.degree. or .lambda./4C relative to the inner transducer, and the delayed signal is combined with the output signal from the other transducer of the pair in a summing amplifier so that only one signal per transducer pair need be sampled by a multiplexer for transmission via a coaxial cable to beamformer apparatus. The concept is applicable to groups of transducers with more than just a pair, i.e., with three or more transducers. Appropriate additional delays are provided with all of the output signals and delayed output signals of a group being received by a single summing amplifier.
    • 被动声纳系统,形成多个接收机波束,用于检测可能的目标。 用于系统的换能器阵列包括多对换能器,每对换能器沿着从中心点发出的大致径向线。 来自每对的外部传感器的输出信号相对于内部换能器延迟90°或λ/ 4C,延迟信号与来自该对的另一个换能器的输出信号在一个加法放大器中组合,因此只有一个 每个传感器对的信号需要通过多路复用器进行采样,以通过同轴电缆传输到波束形成装置。 该概念适用于具有多于一对的换能器组,即具有三个或更多个换能器。 提供适当的附加延迟,所有的输出信号和一组的延迟输出信号由单个求和放大器接收。

    • The invention provides a transducer for use with a conical reflector in which the transducer comprises a frusto-conical radiating member that is coaxially positioned with respect to the reflector member. The half angles of the radiating member and reflectors are related such that every ray from a selected point of interest on the axis that is reflected from the reflector cone to the active surface of the radiating member intersects substantially normally to the active surface.Where the energy is directed to a point of interest distant from the reflector, the half angles are related in accordance with the formula ##EQU1## ; AND, WHERE THE POINT OF INTEREST IS ON THE AXIS, THE HALF ANGLES ARE RELATED IN ACCORDANCE WITH THE FORMULA ##EQU2## where .phi. = CONICAL REFLECTOR HALF ANGLE;.theta. = conical radiating member half angle;R = the radius of the reflector at a point where a ray from the point of interest is reflected normally to the surface of the radiating member; andS = the distance from the radius R intersection on the axis to the point of interest on the axis.
    • 本发明提供了一种与锥形反射器一起使用的换能器,其中换能器包括相对于反射器构件同轴定位的截头圆锥形辐射构件。 辐射构件和反射器的半角相关联,使得从反射器锥体反射到辐射构件的有源表面的轴上的所选择的感兴趣点的每个射线基本上正交于有源表面。
