Abstract: There are provided a radar signal processing method with a clutter suppression calibration function, and a radar sensor applying the same. A radar sensor according to an embodiment of the disclosure includes: a transmitter configured to transmit a radar signal; a receiver configured to receive a reflected radar signal; a mixer configured to down-convert the radar signal received through the receiver into an IF signal; a memory configured to store clutter information; a restoring unit configured to restore a clutter signal from the clutter information stored in the memory; and a calculator configured to remove a clutter signal from the IF signal down-converted at the mixer, by using the clutter signal restored at the restoring unit. Accordingly, it is easy to detect a radar target by removing objects other than a target easily in various indoor environments, and an SNR and a dynamic range may increase.
