Hi everyone
I'm having a problem processing as follows:
I want to measure distance using radio waves .I use two antennas transmit and receive signals. signal transmitted to the obstructions
signal is measured parameters S21, it is the ratio obtained in wave antenna and the transmitting antenna emit waves. S21 parameter depends on the phase of the incident wave and the wave of the transmission time and frequency
signal S21 obtained a matrix of values of the real and imaginary part of it corresponding to each frequency
so now you want to measure the distance d that is how the signal S21 obtained
some guidelines are modified IFFT and d = nλ + x
thanks a lot
