Abstract
This article presents a fully integrated 77-GHz
hybrid time-division-multiplexing multiple-input–multiple-output
(TDM-MIMO) phased-array radar in a 55-nm CMOS process.
The system integrates eight independent transmitters (8 × 1
TXs) and two four-channel phased-array receivers (2 × 4
RXs), achieving a 4 .76× increase in detection range compared
to single-input–single-output (SISO) architecture in long-range
radar (LRR) mode and 1.79 ◦ angular resolution with 16 ×4
virtual array in short-range rad
