智能水雷敌我识别及关键参数分析

为了解决传统水雷对敌我双方都构成威胁的问题，在分析敌我识别技术工作原理的基础上，提出了一种智能水雷敌我识别流程和敌我识别装置实现方法，通过理论分析和仿真研究了声传播损失和传播距离、发射信号中心频率之间的关系，分析了影响水雷识别距离的参数，得出了识别距离应不小于1 km的结论，为未来水雷的智能化改造提供了依据。

Identification friend or foe of intelligent mine and key parameters analysis

In order to solve the problem that traditional mine can be a threat to both sides,an identification friend or foe(IFF) process and a realization method of IFF device for intelligent mine are presented through analyzing the working principle of IFF technology. The relationships between the loss of sound propagation and propagation distance,the center frequency of transmit signal are also studied through theoretical analysis and simulation,and parameters influencing the identification distance are analyzed.The conclusion is drawn that the recognition distance should be no less than 1 km,which provides a certain basis for the intelligent mine transformation in the future.
