摘　　要：首先介绍了UWB成形脉冲的算法,然后基于Hermite矩阵和Chirp信号得到了UWB的成形脉冲。在对Chirp脉冲的带宽、中心频率等性能参数比较分析的基础上,将若干个Chirp脉冲信号进行线性叠加,通过仿真结果表明,随之产生的脉冲信号不仅满足FCC对UWB脉冲信号辐射功率要求,而且其脉冲信号的频谱利用率也很高,同时还能有效抑制对其他窄带系统的干扰。In this paper,an algorithm of the UWB shaping pulse is discussed.Based on the comparison and analysis of the performance parameters of the Chirp pulse,including bandwidth and central frequency,a linear combination of several Chirp pulse signals is proposed by using Hermite matrix.The simulation result shows that the Power Spectral Density （PSD） of the produced pulse is not only according with the Federal Communications Commission （FCC）,but also enjoys a high spectrum utilization ratio.Meanwhile,the pulse can suppress the interference from UWB system to other narrowband systems effectively.
