针对小型平台面临的抗干扰低截获水声通信需求，将水声信道和外部干扰对水声通信的影响概括为乘性干扰和加性干扰并进行梳理分析，并据此围绕基于通信体制的干扰规避、基于信道均衡的乘性干扰消除和基于信道估计的加性干扰抑制对干扰背景下的小型平台水声通信技术进行系统性概述，最后对复杂环境下水下小型平台抗干扰水声通信技术要点和具体应用进行总结。
In response to the anti-interference and low-interception underwater acoustic communication requirements faced by small unmanned platforms, the impact of underwater acoustic channel and external interference on underwater acoustic communication is summarized and classified as multiplicative interference and additive interference. Based on this, a systematic overview of underwater acoustic communication technology for small unmanned platforms under interference backgrounds is provided, focusing on interference avoidance based on communication systems, multiplicative interference elimination based on channel equalization, and additive interference suppression based on channel estimation. Finally, the key points and several applications of robust anti-interference underwater acoustic communication technology for small underwater unmanned platforms in complex environments are summarized.
