摘　　要：研究了编码ＣＷ信号的特性，讨论了Ｇｏｌｄ序列族和Ｋａｓａｍｉ序列族的优良的正交性，给出了这两种正交扩谱序列用于分布式防空雷达系统的数字信号处理机框图。理论分析和仿真结果表明：在多普勒频移较大时，这种处理机在脉冲压缩和扩展多普勒容限方面性能优越。the charactet of the coded CW signal is studied and the excellent properties Of Gold and Kasami sequenee families are distcussed in this paper.The block diagram of the digital signal processor is pre-sented when these two orthogonal spread spectrum sequence frmilies are employed in dispersed radar systems for air defense. The theoretical analyses results of simulation show that under the condition of larger Doppler frequency the processor shares excellent performances on pulse compression and spreading Doppler tolerance.
