Micro-Doppler effect removal in ISAR imaging based on Radon-Laplace method

In inverse synthetic aperture radar (ISAR) imaging, the high-resolution images can be obtained by using Range-Doppler algorithm. However, the rotational parts of the complex moving targets induce micro-Doppler (m-D) effects which influence the quality of ISAR imaging. In this Letter, a novel method of Radon-Laplace based on the Radon transform (RT) and the Laplace operator is proposed to reduce th...
