Abstract: A system includes an analog front-end configured to process a signal to obtain amplified beams, the signal being formed by pulses of a plurality of beams, pulses of each of the plurality of beams being generated according to a time-hopping modulation scheme, a plurality of radars coupled to the analog front-end, the plurality of radars configured to transmit each of the amplified beams at a different angle, and to receive reflections of the transmitted beams, and a plurality of correlators coupled to the plurality of radars through the analog front-end, the plurality of correlators being configured to process the reflections of the transmitted beams to obtain proximity measurements.
