Highly-Integrated Radar Transceiver with 2 TX and 4 RX Channels for Range, Azimuthal and Polar Angle Measurements

A highly-integrated V-band 6-channel radar sensor implemented in Silicon Germanium BiCMOS technology is presented in this paper. The transceiver, which is composed of two transmit as well as four receive channels, is very suitable for multiple-input multiple-output (MIMO) radar systems and can be complemented by 2-D antenna array configuration to enable the measurements of the 2-D and 3-D positions of objects. The fabricated transceiver chip was used to build a MIMO radar system that achieves an azimuthal and a polar angular resolution of 28.6° and 57.3°, respectively.
