中文摘要:
      提出一种利用气枪作为声源的远程水声通信遥控的方法,以扩大水下遥控范围,支持水下多平台、多节点协同工作。从气枪声源产生脉冲信号的声源级、频率和多次发射的一致性等分析了作为水声通信信号声源的可行性;高声源级、低频段保证了脉冲信号在水下可远距离传播;高一致性保证了气枪声源脉冲信号具有可编码性和高的检测正确率。针对指令级远程遥控信息传输需求,提出了时延脉冲编码方法和信号检测识别方法。针对不同水文环境条件进行了仿真分析,为实现远程水声通信遥控提供了一种可选的技术途径,支持水下远距离多节点协同工作。
英文摘要:
      In order to remotely control long–distance underwater acoustic communication and to effectively extend action range, this paper proposes a method of using air-gun as a sound source for underwater acoustic remote control. Taking commercial air-gun as an example, the feasibility of the air-gun used for remote underwater acoustic communication is analyzed from three aspects: sound source level, frequency and consistency. High source level and low frequency ensure that sound pulse emitted by air-gun can be spread over a long range underwater and high consistency ensures that the sound pulse could be coded and detected accurately. According to the need for transmission of the instruction level remote information, the time-delay pulse coding method and signal detection method are proposed. The simulation is carried out in different hydrological conditions, and shows that the proposed methods are an achievable approach to remotely controlled underwater acoustic antagonistic equipment such as acoustic decoy, to provide reliable communication for long distance underwater operation from mother ship and to support cooperative work of far multi-nodes.
