Development of short-range ground surveillance radar for moving target detection

摘要

In this paper, we proposed a short-range ground surveillance FMCW (Frequency Modulated Continuous Wave) radar. For this work, we employed a 2D-FFT algorithm to detect moving targets, and a windowing scheme to reduce the distortion generated by frequency transition. Moreover, we designed a moving target finding method to extract moving targets from the remaining distortions. We developed a 24GHz FMCW radar system comprised of front-end and back-end modules. A newly designed algorithm was implemented in a micro-processor of the back-end module. When we tested the function of the developed radar system in the field, the range and velocity profiles of a moving car occupying the detection zone were extracted without distortion.
