- hese problems, the antenna steering technique is employed in the TOPS mode. The azimuth antenna
beam is rotated throughout the acquisition from backward to forward, acquiring very long bursts.
After finishing the scan of the sub-swath 1, the look angle is changed to illuminate the sub-swath 2,
performing the scan from backward to forward again.ReadRasterFileNew.rar
- In conventional ScanSAR mode, targets located at different azimuth positions are illuminated
by different parts of the azimuth antenna pattern (AAP), resulting in problems of scalloping,
and azimuth-varying distributed target ambiguity ratio and signal-to-noise ratio (SNR).important article.rar
- Based on the terrain observation by progressive scans (TOPS) mode, an efficient
full-aperture image formation algorithm for focusing wide-swath spaceborne TOPS data is proposed.
