I have a microwave radio link where the transmitter and receiver are linked together by a common clock.
The transmitter upconverts a baseband low-frequency i/q signal to a higher frequency and this is sent out to the receiver which down-converts it to the same i/q frequency.
With the transmitter and receiver spaced distance d0 apart there is a particular amplitude attenuation and phase (say amp_0, phi_0), whereas if the transmitter and receiver spaced distance d1 there is another amplitude phase response (say amp_1, phi_1). The amplitude difference is easy to calculate; however how could one calculate the phase difference, phi_1 - phi_0?
The reason for doing this would be to be able to compute/verify the spacing change between the transmit and the receive through the measurement of the phase difference...
Any thoughts?
Thank you!
