Fixational eye movement radar: Random spatial modulation

It was recently shown that it is possible to mimic the passive actuation of the human eye, otherwise known as fixational eye movement (FEM), using an active MIMO FM radar emission and associated receive processing. Given that biological FEM possesses an inherent randomness, here the use of FM noise radar waveforms and random spatial jittering are incorporated into this active emission structure to realize FEM radar (FEMR). Note that in contrast to standard beam dithering or MIMO radar, FEMR forms a completely coherent beam that varies spatially with time. It is shown that FEMR intrinsically enhances spatial resolution in both azimuth and elevation relative to standard (fixed) beamforming using only matched filter processing.
