| Abstract: | 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. |
