Abstract
A device includes a transmitter coupled to an antenna, a receiver coupled to the at least one antenna, and a processing device to: cause the transmitter to radiate a radio frequency (RF) signal; receive, via the receiver, a reflective RF signal based on the radiated RF signal; detect, within a data array of the reflective RF signal, a maximum peak among a plurality of signal peaks, the maximum peak being indicative of a first distance to a first object relative to the at least one antenna; and cancel, using cascading peak cancellation on the spectrum, the maximum peak while detecting a first next-highest peak of the plurality of signal peaks compared to the maximum peak, the first next-highest peak being indicative of a second distance to a second object.
