Abstract: In accordance with an embodiment, a method includes: obtaining a magnitude of a frequency spectrum of a receive signal of the radar sensor, wherein the frequency spectrum comprises a first portion and a second portion within a frequency bandwidth divided into bins, and wherein the first and second portions are symmetrically positioned with respect to a center frequency; for at least one bin in the first portion, determining a bin threshold based on the magnitude of the frequency spectrum within one or more bins in the second portion; for at least one bin in the second portion, determining a bin threshold based on the magnitude of the frequency spectrum within one or more bins in the first portion; and detecting a target motion in response to the magnitude of the frequency spectrum exceeding the bin threshold in at least one bin within the frequency bandwidth.
