摘要: 为解决主动声纳系统易暴露、隐蔽性差的问题,提出一种基于海豚whistle信号的仿生主动声纳隐蔽探测技术。在发射端将线性调频探测信号隐蔽在海豚whistle信号中,设计了一种主动声纳的仿生隐蔽探测信号,该信号与海洋中的海豚哨叫声十分相似,可以利用海洋中的生物环境噪声实现主动声纳的隐蔽探测。在接收端选用自适应相关器作为主动声纳的时域处理器,自适应相关器对海洋环境有较强的匹配适应能力,可以自动匹配海洋信道,有效抑制多途扩展损失,相较匹配滤波器有更高的信噪比处理增益,有助于实现远距离探测。仿真和海试结果表明,基于海豚whistle信号的仿生主动声纳隐蔽探测技术具有良好的隐蔽性和有效性。

Abstract: To solve the poor covert of active sonar detection system, a bionic active sonar covert detection technology is proposed on the basis of dolphin whistle signals. At the transmitting terminal,the LFM signals are hidden in dolphin whistles to design an covert active sonar bionic detection signal. This signal is similar to dolphin whistles in the ocean,so we can use the biological environmental noise in the ocean to achieve active sonar covert detection. At the receiving terminal, the adaptive correlator is used as an active sonar processor. The adaptive correlator has a strong ability to match the marine environment. It can automatically match the marine channels, and reduce the multipath spreading loss effectively, thus getting higher signal-to-noise ratio processing gain than the matching filter. The adaptive correlator contributes to long-range detection. The simulation and the sea experiment proof the covertness and effectiveness of the proposed bionic active sonar covert detection technology based on dolphin whistle signals.

Key words: acoustics, bionic active sonar, covert detection, adaptive correlator, dolphin whistle signal
