Abstract
A radar system comprises a plurality of antenna sub-systems, each operable to transmit and receive radio frequency (RF) signals in a corresponding sector, wherein the plurality of antenna sub-systems are positioned such that the corresponding sectors cover a total range of about 180 degrees to about 360 degrees without rotation of the radar system. The radar system also comprises shared backend circuitry coupled to each of the plurality of antenna sub-systems and operable to process signals from each of the plurality of antenna sub-systems to detect the presence of an obstacle in one of the corresponding sectors.
