i use two antenna (Transmitter and reciever) to caracterize some materials. i use a sweep of 30 frequencies in the frequency range:f=[5 6]GHz. what should i get when i want to get the ifft of this sweeps?
the VNA send f1,f2......f30 successively. that mean in the time damain cos(2*pi*f1*t) ,cos(2*pi*f2)......cos(2*pi*f30).
