摘要
敌我识别系统的核心技术之一是询问信号与应答信号的加密传输,针对信号传输中对密码的要求,文中引入了伪随机码,基于剪接筛法设计了能产生2048个两两相异的5级M序列的电路,并对该电路进行了仿真,仿真结果验证了该设计的正确有效性.
One of the kernel technologies in IFF is the encrypting transmission for the questioning and answering signal. In this paper,to meet the requirements of cipher in the signal transmission of IFF system,the pseudo-random code is introduced.A new generating circuit on five-level M-sequence based on the cut-join sieve method,which can generate 2048 different five-level M-sequences.is proposed.It has been proved through the simulation that the designed genera- ting circuit is valid.
