| 摘要: |
| 针对敌我识别系统在现代战争中的保密要求，提出一种将马尔科夫系统识别技术应用于敌我识别的新方法，每个发射机按照系统分配的转移矩阵发射随机码，接收机利用已知的不同我方作战单元的转移矩阵，判断码序列所属，实现我方目标的识别。与传统方法相比，发射机每次按照一定的转移概率发射服从马尔科夫分布的随机编码，大大提高了敌方截获和破译的难度，提升了系统的抗欺骗干扰性能。仿真结果表明，该方法在发射序列比较长的情况下，可以获得准确的识别结果。 |

| Abstract: |
| According to the secrecy requirement of IFF(Identification between Friend or Foe) system in modern wars, a new IFF method based on Markov system identification technique is proposed.In accordance with certain transition matrix distributed by the system,each transmitter launches random code. With the prior information of transfer matrices, the receiver identifies the units according to the code sequences via the Markov system identification technique. Compared with the traditional methods, this method transmits codes obeying Markov distribution randomly at each time, which can greatly improve the intercept and deciphers difficulty, and increase the system's robustness. Simulation result shows that given a relatively long sequence, this method can accurately identify different codes. |
