From: Directional amplitude backscatter modulation with suppressed Doppler based on rotating resonant loop
The magnitude and phase of the measured amplitude modulating waveform for (a) symmetrical, (d) non-symmetrical rotation of the loop compared with those predicted by the model. The measured PSD of the received signal backscattered from (b) symmetrically, (e) non-symmetrically rotating loop. The calculated Fourier coefficients of the time-varying complex envelope of the backscattered field from (c) symmetrically, (f) non-symmetrically rotating loop.
