| Abstract: | The core technology in the design of IFF(Identification Friend or Foe)system is how to generate the cipher,and this is dealt with in the paper.The prototype circuit of producing KM clock-controlled sequence,a pseudorandom sequence suitable for IFF system,is developed. It is composed of the followings:IFF system clock,generator of KM clock-controlled sequence, the system for level shift,equalifying and classifying of KM clock-controlled sequence,fraction- al frequency,counter,comparator and registor.Eight bit address code is used in the circuit,and the addresses of the direct spreading code(DS code)groups are displayed by luminescence diodes adopted. |
