[en] A novel Phase Center Motion (PCM) based
technique for discriminating angle-Doppler signatures within
Multiple-Input-Multiple-Output (MIMO) radars using Frequency
Modulated Continuous Wave (FMCW) has been explored
in this work. The PCM technique induces angle dependent
Doppler shifts in the back-scattered signal, wherein a modified
Doppler post processing for FMCW leads to joint angle-Doppler
processing. Specifically, we intend to design unique spatialtemporal motion of the phase center on each individual MIMO radar channel in an effort to synthesize nearly orthogonal angle-Doppler signatures. Subsequently, we also develop a MIMO radar receiver design, which would be capable of discriminating between these induced angle-Doppler signatures. The asymptotic investigation provides a Bessel function characteristic. Simulation results demonstrate a significant side-lobe suppression of 8:5 dB for an individual PCM trajectory and 7 dB over distinct PCM trajectories, in an attempt towards realization of nearly orthogonal MIMO radar channels.
