1. An electronic device comprising:
a signal generator configured to generate a first radio-frequency signal having a first waveform and a second radio-frequency having a second waveform, the first waveform and the second waveform having non-overlapping frequencies as a function of time;
a first antenna configured to transmit the first radio-frequency signal;
a second antenna configured to transmit the second radio-frequency signal concurrent with transmission of the first radio-frequency signal by the first antenna;
a set of one or more antennas configured to receive a reflected version of the first radio-frequency signal and a reflected version of the second radio-frequency signal, wherein the set of one or more antennas is different from the first antenna and the second antenna; and
one or more processors configured to identify a location of one or more external objects based on the reflected version of the first radio-frequency signal and the reflected version of the second radio-frequency signal received by the set of one or more antennas.
