摘　　要：根据Rayleigh脉冲峰值频率与脉冲形状参数α、求导阶数n的关系提出了一种设计超宽带脉冲的新算法。不像其它算法只能设计出一个脉冲,本算法可以设计出无数个满足FCC频谱规划的脉冲,即能够求出所有满足条件的α值,并给出了α的取值范围。A new pulse design algorithm was proposed to generate UWB pulse based on the relation among the peak frequency of Rayleigh monopulse, the pulse shape parameter α and the order of differentiation n. Not like other algorithms that only work out one pulse, the proposed algorithm can lead to the design of a myriad of pulses that are compliant, namely, it can figure out all α which satisfy the regulation and give out the range of α.
