Abstract

Ground moving trains have been imaged by many airborne and spaceborne SAR systems, but seldom imaged by ground-based radar system. In this paper, we introduce our experiment on moving train imaging by a ground-based Ka-band radar system with 1 GHz bandwidth. The 1 GHz bandwidth is realized by synthesizing 10 subpulses in frequency-jumped burst (FJB). High-resolution SAR images for a moving train were obtained and the electromagnetic scattering characteristics were analyzed. Radar images show that at different aspect angle, the strong scattering centers are different and may changeable.
