Multipath Smearing Suppression for Synthetic Aperture Radar Images of Harbor Scenes
IEEE Access, 2019 Due to the periodic and non-periodic variations in the sea surface, smearing is caused by the multiple paths between the sea surface and man-made objects in synthetic aperture radar images of harbor areas. This smearing can cover real targets and lead to

Classification of Automotive Targets Using Inverse Synthetic Aperture Radar Images [PDF]
IEEE Transactions on Intelligent Vehicles, 2022 We present a framework for simulating realistic inverse synthetic aperture radar images of automotive targets at millimeter wave frequencies. The model incorporates radar scattering phenomenology of commonly found vehicles along with range-Doppler based clutter and receiver noise. These images provide insights into the physical dimensions of the target,
