    Harmonic clutter recognition and suppression for automotive radar sensors by Jae-Eun Lee, Hae-Seung Lim, Seong-Hee Jeong, Hyun-Chool Shin, Seong-Wook Lee, Seong-Cheol Kim

    Published 2017-09-01
    “…In this article, we propose a novel harmonic clutter recognition and suppression method to overcome the deterioration of a target- or vehicle-detection performance due to harmonic clutters. Although several studies have been performed on the reflection and diffraction on road surfaces for automotive radar sensors, most of them did not consider the case where metallic structures such as iron tunnels with greater reflection are densely distributed. …”
