A 79GHz 4RX-2TX SiGe-Integrated Sequential Sampling Pulse Radar

Abstract

A 79GHz, SiGe-integrated, multiple-input multiple-output (MIMO) sequential sampling pulse radar is presented. The radar sensor is equipped with two transmit channels and four coherent receive channels and is manufactured in a 250GHz fT SiGe BiCMOS technology. The fabricated chip is tested by in-system measurements using a uniform patch antenna array, which is fabricated on an RF PCB.
