Abstract

This paper presents a complete phase-based radar system operating at 155 GHz which employs a non-coherent approach to ranging, offering the major advantage that frequency synthesizers are not needed in the Tx and Rx. This enables the possibility of multi-pixel radar systems through a 51% reduction of total system power vs. similar coherent radar. The proposed radar system achieves sub-centimeter target position accuracy and consumes only 220mW per radar channel (excluding commercial phase detector) in a 65nm CMOS technology.
