摘　　要：UWB技术在卫星通信领域推广应用的瓶颈是UWB卫星通信系统与窄带系统的互扰问题。研究了正弦调制高斯脉冲在卫星信道应用的时频域特性,提出了Ka频段UWB卫星通信信道模型,建立UWB卫星通信仿真系统,研究了UWB卫星通信系统和窄带系统在互扰条件下的误码特性,得到了影响互扰的关键因素,提出了适合卫星通信信道传输的UWB信号设计参数,论证了UWB卫星通信系统与窄带系统共享频谱的可行性。The bottleneck of UWB technology used in satellite communication field is the interference problem between UWB satellite communication systems and narrowband systems.The time and frequency characteristics of sinusoidal modulation Gaussian pulse used in satellite channel are investigated.UWB satellite communication emulate system is finished and the bit error characteristic in condition of interference between UWB satellite communication systems and narrowband systems is evaluated.Key factors that affect interference are gained and UWB system design parameters that suit with transmission in satellite communication channel are put forward.The feasibility of sharing frequency spectrum between these two kinds of systems is demonstrated.
