摘　　要：随着水中兵器技术的逐步发展,近海沿岸防御敌水下小目标渗透入侵的问题已经越来越严峻。为掌握水下小目标的信号特性,论文以蛙人为研究对象,组织蛙人在水下以悬浮停留和运动前行两种不同的姿态进行试验,对背景环境噪声和蛙人水下声信号进行数据采集。并对其时域、频域以及时频谱信号进行分析,研究出蛙人水下的声信号特性,期望为蛙人被动警戒系统的研制提供参考。With the gradual development of underwater weapon technology,the problem of defending against the penetration and invasion of underwater small targets by the enemy along the coast has become more and more serious.In order to master the sig⁃nal characteristics of underwater small targets,This paper takes the frogman as the research object,organizes the frogman to con⁃duct experiments in two different attitudes of suspension and moving forward,and collectes the background environmental noise and underwater acoustic signals of the frogman.The time domain,frequency domain and time spectrum signals are analyzed,and the un⁃derwater acoustic signal characteristics of the frogman are studied,which is expected to provide a reference for the development of the frogman passive warning system.
