Ambiguity Function of a continuous signal

Hi,

I am trying to create an ambiguity function. I am receiving DVB-T2 signals via two antenna, saving the received data in a .bin file. I already found the function afmag = ambgfun(x,y,Fs,PRF), however it is not suitable for my purpose, since DVB-T2 is a continous signal, therefore PRF doesn't make much sense here.

Ambiguity functions like these should be created: https://www.researchgate.net/figure/Typical-off-air-FM-ambiguity-function_fig1_224361482

Is it possible to create an ambiguity function of a continous signal source like FM radio, DVB-T2, ect.?
