Advances in compact integrated multichannel millimeter wave radar systems using SiGe BiCMOS technology (Focused session on highly-integrated millimeter-wave radar sensors in SiGe BiCMOS technologies)
In this publication an overview of the recent developments regarding compact multichannel radar systems is given. The chosen radar systems are all based on custom integrated circuits reported in literature from 2010 to 2017. Important specifications of the radar systems are compared to a 120 GHz SiGe:C based 2×8 FMCW MIMO radar sensor reported by us in in 2017 . The technological differences of the integrated circuits used throughout the compared radar systems are discussed with respect to their advantages and disadvantages.
