摘要
文中将峰值处具有非奇异高阶导数值的任意对称单峰瞬时信号形成的复源脉冲波束,表示成关于乘方波系列基本信号(包括短形、三角形、半椭圆等信号)的基本复源脉冲波束场叠加,统一了对称单峰瞬态信号复源脉冲波束的分析公式,并与单边付里叶变换定义的复源泳冲波表达式作了对比。
This paper presents the complex source pulsed beam formed by thearbitrary symmetric single-peak transient signal of normal high-order derive-tives at the peak as the sum of basic complex source pulsed beam about series ofbasic signals including retangular,triangular,and half-elliptical signals of mul-tiple power function. And it uniforms the analysis formulas of the complex sourcepulsed beams of symmetric single-peak transient signals. And it is compared withthe expression of the complex pulsed source beam diffident by the single-side fou-rier transform.
