摘　　要：为了解决普通的激光敌我识别中,信号容易被侦收后破解的问题,提出了一种基于加密模式的协同式激光敌我识别技术,对激光敌我识别系统工作原理进行了研究与分析,采用通过时间信息产生一组伪随机数,利用一组高强度的改进加密算法对这组伪随机数进行变换产生加密数据,并经过扩频函数对变换后的加密数据进行扩频,结合RS纠错码产生最终编码的方法,增强数据的抗干扰能力,经实验测试实现了提高信号保密性和安全性的目的,为激光敌我识别的发展提供了新的思路。In order to solve the problem that the signal is easily detected and deciphered in general laser Identification,Friend or Foe(IFF),a cooperative laser IFF technology based on encryption mode is proposed.The working principle of laser IFF system is studied and analyzed.The time information is used to generate a set of pseudo-random numbers.A set of high-strength improved encryption algorithm is used to transform the pseudo-random numbers to generate encrypted data,and the encrypted data is spread by the spread-spectrum function.Combined with the Reed-Solomon(RS)error correction code,the final code is generated to enhance the anti-jamming ability of the data.Experimental results show that the signal confidentiality and security are enhanced,and it provides a new idea for the laser IFF development.
