摘要
星载扫描波束合成孔径雷达（ＳｃａｎＳＡＲ）技术可以扩展星载合成孔径雷达一次通过观测地区时的观测带宽度。对ＳｃａｎＳＡＲ成像的天线波束位置数目、扫描角度范围和方位分辨率等性能进行了分析，阐述了ＳｃａｎＳＡＲ的某些设计考虑。
The ScanSAR technique would allow the SAR system to produce images of a swath of as much as 500km in a single pass of the satellite, compared with the maximum width of about 100km with a single beam in wide swath mode. The number of possible scanned beam positions, avaiable scan angle range, azimuth resolution, and the some design considerations of ScanSAR imaging are explained in this paper. The example for the ScanSAR imaging is also described.
