摘要：
In this paper, millimeter-wave frequency modulated continuous wave (FMCW) imaging of foreign object debris (FOD) which is potential hazard on airport runway is studied with the help of Spotlight Circular Synthetic Aperture Radar (SC-SAR) system. First, the signal model of FMCW SC-SAR is analyzed. Then, a novel imaging algorithm with random phase error mitigation is developed by virtual of the advanced Range-Doppler method and phase gradient autofocus (PGA). Finally, the experimental results arc presented to show the validity of our proposed imaging method for the FMCW SC-SAR system with random phase error.
