High Resolution Moving Train Imaging Experiments with Stepped-Frequency Radar System

Inhalt:
In this paper, the experiment system for high resolution moving train imaging is introduced. For the experiments, there are three objectives: realizing moving targets imaging as an inverse synthetic aperture radar; verifying the effects of range profile resolution improvement by stepped-frequency; comparing the dechirp and matched filtering methods. During experiments, moving train imaging results have been attained via two imaging methods. The differences of imaging results by two methods are shown respectively. The objective for verifying improvement on range resolution by stepped chirp is realized.
