前言 主要记录下常用各种子波函数以及对应的图形。 Ricker子波 $ S(t)=(1-2\pi^2f^2t^2)exp(-\pi^2f^2t^2) $ 1 2 3 function [w] = ricker(fpeak,t,tdelay) w = exp(-pi^2*fpeak^2*(t-tdelay).^2).*(1-2*pi^2*fpeak^2*(t-tdelay).^2); return Ricker子波的一阶导数: $$S(t)=2\pi^2f^2t(2\pi^2f^2t^2-3)exp(-\pi^2f^2t^2)$$ 1 2 3 4 function [w] = ricker1(fpeak,t,tdelay) w =
