| Abstract: | According to the characteristics of the frequency modulated continuous wave（FMCW） synthetic aperture radar（SAR） and its signal model,the imaging method of the frequency scaling algorithm in FMCW SAR was researched in this paper.The correction compress treatment for the range migration in the algorithm was given out,and so was the flowchart of the algorithm.The simulation results of some point target showed that this algorithm was effective. |
