    • A guided underwater object (GUO) (100) comprises steering means, an on-board guidance system (200) for controlling the steering means, and a hydrophone unit or units (104A, 104B, 104C, 104D, 104E, 104F, 104G, 104H) arranged to pass signals induced therein by an acoustic guiding beam to the on-board guidance system to effect directional control of the self-propelled underwater object. The GUO is guided by a remote guidance system characterized by a plurality of transmitter arrays (402A, 402B, 402C, 402D; 412A, 412B, 412C, 412D; 422P, 422Q, 422R) arranged to transmit a plurality of contiguous acoustic beams (302A, 302B, 302C, 302D) each having a different frequency or frequency chirp (or other acoustic signal coding) and enclosing a guidance corridor of lower sound level (‘null’) (304) extending approximately in the direction of propagation of the acoustic beams and defining a flight path of the object. The GUO requires no on-board search sensors, no communications link with the guidance system and is of low cost.
    • 引导水下物体(GUO)(100)包括转向装置,用于控制转向装置的车载引导系统(200)和水听器单元(104A,104B,104C,104D,104E ,104F,104G,104H),其布置成将由声引导梁引导的信号传递到车载引导系统,以实现自推进水下物体的方向控制。 GUO由远程引导系统引导,其特征在于多个发射机阵列(402A,402B,402C,402D; 412A,412B,412C,412D; 422P,422Q,422R) 每个具有不同频率或频率啁啾声(或其它声信号编码)的邻近声束(302A,302B,302C,302D)并且包围较低声级的引导走廊(“零”), )(304)大致沿着声束的传播方向延伸并且限定物体的飞行路径。 GUO不需要车载搜索传感器,与引导系统无通信连接,成本低廉。
