摘　　要：超宽带系统中的关键技术之一是脉冲波形的设计。为了获得可以在全频段中逼近辐射掩蔽标准的波形,介绍了超宽带系统和脉冲波形的概念与特点,考虑通过高斯脉冲不同导函数的线性组合来寻找最优波形,并对归一化高斯脉冲导函数的线性组合进行了MATLAB仿真研究。最后,通过对仿真结果进行分析,得出了相应的结论。The design of pulse waveforms is one of the key technologies in ultra-wideband systems.In order to obtain waveforms that can approximate the radiation masking standard in the full frequency band,the concepts and characteristics of ultra-wideband systems and pulse waveforms are described.The linear combination of Gaussian pulse different derivative functions is used to find the optimal waveform,and the liner combination of normalized Gaussian pulse derivative functions explored by MATLAB simulation.Finally,based on analysis of the simulation results,the corresponding conclusions are drawn.
