- Abstract
Terrain Observation by Progressive Scans (TOPS) is the spaceborne wide swath synthetic aperture radar (SAR) imaging mode and attractive for ocean remote sensing. Its imaging processors are quite different from the one of the conventional stripmap mode due to antenna beam progressive scanning. This paper proposes a new imaging processor in TOPS for moving targets especially for moving ships in ocean. In addition to resolving the azimuth aliasing problem in TOPS, the Doppler parameter estimation is the key point of the proposed processor. According to the estimated Doppler parameters, some transfer functions of the processor should be updated. Simulation results on point and distributed targets validate the proposed imaging processor
