Micro‐Doppler effect removal in inverse synthetic aperture radar imaging based on UNet
Electronics Letters, Volume 59, Issue 9, May 2023., 2023 The micro‐Doppler (m‐D) effect caused by the rotational parts of the targets influences the quality of inverse synthetic aperture radar (ISAR) imaging. In this letter, a novel deep network‐assisted method is proposed to reduce the m‐D effect in ISAR imaging.
