| Abstract: | Spaceborne synthetic aperture radar(SAR) is a kind of modern high resolution sidelooking imaging radar. Making use of the techniques of the synthetic aperture,pulse compression and digital information processing,it obtains high resolution in azimuth direction and in range direction. In this paper,the present situation and development trend of spaceborne SAR are summarized. The main techniques of SAR are disscussed,which include spaceborns SAR patterns and systems,and information processing and imaging processing of SAR digital image. Finally, the imaging results using SEASAT-A satellite SAR raw data are provided. |
