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.

当仅收到一个数据向量时，如何正确使用MATLAB歧义函数（AMBGFUN）中的构建？而不是两个，对公式。它仍然适用于合成信号，至少我尝试的那个信号。我不明白如何。

thak你发表我的问题。

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!!

嗨，亚历克斯，

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,...)
