Millimeter-wave (MMW) radar, which is used for road feature recognition, has performance that is superior to optical cameras in terms of robustness in different weather and lighting conditions, as well as providing ranging capabilities. However, the signatures of road features in MMW radar images are quite different from that of optical images, and even(More)
From the view of electromagnetic scattering, it is indicated that the micro-Doppler (m-D) characteristics of an extended target undergoing micro-motions are actually induced by the change of incident directions of radar pulses. Different micro-motions may lead to similar change of incident directions, consequently inducing similar m-D characteristics. To(More)
