As the azimuth beam sweeps at high squint angles, the real difficulty in processing high
squinted terrain observation by progressive scans (TOPS) data is the azimuth spectrum …

For the squinted terrain observation by progressive scans (TOPS) imaging mode, three
problems need to be considered: azimuth spectrum aliasing, serious range-azimuth …

Aiming at solving the azimuth signal aliasing problem in the Doppler domain, the azimuth
time aliasing problem after range cell migration correction (RCMC) and the severe range …

Abstract Squint Terrain Observation by Progressive Scans (TOPS) SAR imaging mode is
confronted with three issues: azimuth spectrum aliasing, severe range-azimuth coupling and …

During the data acquisition of a squint terrain observation by progressive scan (TOPS)
synthetic aperture radar (SAR), the steering of the antenna main beam increases the …

The linear range walk yields a significant range-azimuth coupling effect in a highly squinted
synthetic aperture radar (SAR). Although the linear range walk correction (LRWC) technique …

This paper focuses on the data processing of highly squinted sliding spotlight and Terrain
