With regard to stepped frequency radar, what does it mean when we say that the transmitted signal is "demodulated in a quadrature sense"?
The property of interest in this kind of radar is the phase difference. We basically obtain a phase delayed version of the Tx signal on receiving.
How does "demodulating in I/Q sense" help convert the phase difference into distance information?
I understand basic digital I/Q modulation.
Any help is highly appreciated!
