摘　　要：基于完全互补码良好的自相关性和互相关性,将完全互补码作为扩频序列运用到雷达通信一体化的设计中,建立了基于完全互补码的一体化信号模型以及系统结构。通过对完全互补码的多普勒频移特性仿真分析,证明了它在一体化系统中的优越性,并且探究了在不同脉宽条件下扩频因子对系统性能的影响。最后针对回波遮掩问题,提出采用子码匹配滤波的方式对一体化波形进行优化。In this paper, the design of integrated radar and communication systems is considered in which complete complementary codes served as spread spectrum sequences. Based on complete complementary codes which have ideal autocorrelation property and cross-correlation property, an integrated signal model and a system structure are established. The simulation results show that complete complementary codes have an excellent characteristic with Doppler shift. Additionally, the influence of spreading factor on the performance of system under different pulse widths is explored. A sub-code matched filtering method is provided to react to echo eclipse in the end.
