Imaging for Bistatic Airborne Frequency Modulated Continuous Wave SAR

Frequency modulated continuous wave synthetic aperture radar (FMCW SAR) has become one of the main SAR research directions for its small size, light weight and high resolution, which is suitable for air-borne or UAV-borne SAR imaging. In this paper, a FMCW SAR structure is proposed, the transmitter and receiver are placed at the same flying path, separated with a constant distance to attain good isolation. The simulation result is presented for SAR imaging.
