The displacement measurement with frequency‐modulated continuous‐wave radar based on radar interferometry technique has attracted growing interest in recent years. One of the main challenging issues is the static clutter interference in the same range bin, which results in amplitude shrinkage. A novel approach from signal processing side is proposed, i.e. implementing a post‐processing procedure based on phasor offset compensation, which can be formulated as a circle fitting problem regarding phasor representation. Both simulated and experimental results are provided to validate the effectiveness and superiority of the proposed technique.
