A novel frequency‐modulated continuous‐wave radar‐based power line detection method exploiting the Bragg angle

Abstract

AbstractA novel power line detection method exploiting the Bragg point of power line is proposed in this paper. First, the radar echo of power line is divided into multi‐band along the frequency dimensional with incomplete repetition at equal intervals. Then, the candidate power lines in the echo of each frequency band can be found exploiting the Hough transform and constant false alarm rate (CFAR). Since the Bragg angle of the power line will change with frequency while that of the artefacts is fixed, the power lines can be easily detected from the background by exploiting unique frequency feature of Bragg angle of power line.
