Abstract
ABSTRACTThe carrier platform in synthetic aperture radar (SAR) imaging may deviate from the correct trajectory due to end currents in the atmosphere, causing motion errors and ultimately degrading the quality of the radar image. Techniques for motion compensation can reduce the impact of motion errors on the results of the imaging process. Motion error parameters are necessary for motion compensation algorithms. In this paper, the line of sight (LOS) error of the carrier platform is estimated based on the vortex-selected SAR imaging system by analysing the vortex SAR echo data using the relationship between the Bessel magnitude term, the phase term, and the motion error. The validity of the method is verified through numerical simulations.KEYWORDS: Electromagnetic vortexmotion error estimationSAR imaging Disclosure statementNo potential conflict of interest was reported by the author(s).Additional informationFundingNational Natural Science Foundation of China (61961033).
期刊介绍：
Remote Sensing Letters is a peer-reviewed international journal committed to the rapid publication of articles advancing the science and technology of remote sensing as well as its applications. The journal originates from a successful section, of the same name, contained in the International Journal of Remote Sensing from 1983 –2009. Articles may address any aspect of remote sensing of relevance to the journal’s readership, including – but not limited to – developments in sensor technology, advances in image processing and Earth-orientated applications, whether terrestrial, oceanic or atmospheric. Articles should make a positive impact on the subject by either contributing new and original information or through provision of theoretical, methodological or commentary material that acts to strengthen the subject.
