help! Fit envelope for a signal spectrum# Computation - 科学计算

Have a pulse signal spectrum. The outline is like
(sin(pi*w*sin(theta)/lambda)/(pi*w*sin(theta)/lamda))^2. But under the
outline, there are a few pulse signal.
But don't know how to fit the envelope for it. Think the envelope function is
(sin(pi*w*sin(theta)/lambda)/(pi*w*sin(theta)/lamda))^2. But what the
mathematic relationship between the signal and the envelope? I can find the
mathtools like mathcad, matlab and mathematica. So if there is any code of
them, it will be more helpful.
Thanks.
