How Can I express(implement) precise replica when I draw a wideband ambiguity function?

Hi. Everyone!

Nowadays I'm trying to draw wideband ambiguity functions for radar, sonar waveform design.

In literature, there are two types of amibiguity functions(AF). Narrwoband and Wideband.

I understand that if signal satisfies narrwoband assumption, narrowband AF could be used and its implementation is simple.

However.... Wideband AF is different I think because its replica term expressed as bellow:

I mean that how could I implement replica signal in matlab ??

Hello. I am trying to make this also. I couldnt find yet. Matlab's default "matrix resize function" would be good for 'alpha' scaling factor. But I am not sure. If you cand sucseed I would be hapy to hear from you. ([e-mail])
