Hello. I am gathering data for studying possibilities of passive multistatic radar for my graduating work. I am using RTL-SDR modules (hardware) and SDR# (software) for recording real radiosignal. It creates file with two data vectors for I and Q components of signal (real and imaginary). Formulas of Ambiguity function in all works i found related to my subject also uses both real and imaginary parts of signal.
How do i correctly use build in Matlab Ambiguity function (ambgfun) when it receiving only one vector of data? Instead of two, acording to formulas. It still works good for synthetic signal, at least those one which i tryed. I do not understood how.
Thak you for atention to my problem.

Hi,Man. u can use real() or imag() function to get one vector of data, then use the ambgfun() to get the result, just help ambgfun(), then u will konw how to use the fuction.
now can u share the Scenario, its my graduate works, i'm build the Scenario. can u give some advices? thank u!!

Hi Alex,
It will be great if you could somehow share your formula. In general, I and Q channel are often, like you said, the real and imaginary part of the signal, so you could consider to pass in I+1i*Q into the function, i.e.,
ambgfun(I+1i*Q,...)

Hi Alex, You can also use RTL-SDR directly with MATLAB and Simulink using the Communications System Toolbox Support Package for RTL-SDR Radio .
