(ISS) releasing one unit and three models from Kansas-based Ainstein. The OFDM radar system has only been performance verified for a single user and since Doppler measurement is not easily repeatable, it is thus unreliable to use measurement verification for performance observation purposes of a real scenario. The short-term shift orthogonality avoids mutual interferences from the radar echoes of closely spaced scatterers, while interferences from more distant scatterers are suppressed by digital beamforming on receive in elevation.
