Abstract
An electronic device includes M separate radar transmitters and N separate radar receivers co-located in the electronic device, where the M radar transmitters and the N radar receivers are arranged in a circular architecture providing 360° coverage in a horizontal plane. Moreover, the N radar receivers are synchronized, e.g., using a clock signal. During operation, subsets of the M radar transmitters sequentially transmit radar signals and, when a given subset of the M radar transmitters is transmitting, at least a subset of the N radar receivers performs radar measurements. Furthermore, at least the subset of the N radar receivers can perform the radar measurements using circular beamforming. Based at least in part on the radar measurements, the electronic device determines a location of an object in an environment around the electronic device, where the location includes a range and an angular position.
