Claim 0:
1. A smart device comprising:
a radar system including:
a transceiver configured to:
be coupled to at least one antenna;
transmit, via the at least one antenna, a radar transmit signal; and
receive, via the at least one antenna, a radar receive signal, the radar receive signal including a portion of the radar transmit signal that is reflected by a user, the radar receive signal causes the transceiver to become saturated such that the radar receive signal comprises a saturated receive signal, the saturated receive signal comprising an analog signal having a clipped amplitude that is constrained by an upper bound or a lower bound, the upper bound or the lower bound causing the amplitude of the analog signal to be relatively constant at the upper bound or the lower bound for a portion of the analog signal; and

a saturation compensation module coupled to the transceiver and configured to generate, based on the saturated radar receive signal and using a machine-learned module, a predicted signal, the predicted signal comprising a sinusoidal signal.
