The combination of ground-based synthetic aperture radar(GB-SAR) and frequency-modulated continuouswave(FMCW) technology produces a high-resolution remote sensing system that is superior in deformation measurement. However, conventional focusing algorithms should be modified for GB-SAR geometry and FMCW signals. In this paper, an accurate GB FMCW SAR signal model is constructed, and a modified Omega-K algorithm is proposed to achieve optimal imaging. The algorithm is validated by simulation results.
