| Abstract: | Frequency-modulated continuous-wave (FM-CW) synthetic aperture radar (SAR) is a newly proposed imaging radar system, which combining FM-CW technique with synthetic aperture imaging methods has the advantages such as small cubage,light weight, cost-effective, high-resolution, etc. In this paper, the characteristics of FM-CW SAR imaging system and signal processing are summarized. The key problems in the course of FM-CW SAR system development are analyzed. Several application backgrounds of FM-CW SAR and its primary parameters are concluded. Finally, the further development trend of FM-CW SAR based on its development progress is discussed. |
