| Abstract: | For pseudo code ranging,it is found that the two-speed,short-period sequence spread spectrum can implement rapid ranging and tracking,which is suitable for capturing any targets moving at high speed.The basic principles,structure and nature of the two-speed,short-period sequence spread spectrum is analyzed,and the design is presented.Simulink was used for simulation of the system for generating the sequence. |

| Keywords: | direct sequence spread spectrum m sequence composite code low-speed code high-speed code ranging |
