| 英文摘要 | Two approximations, center-beam approximation and reference digital elevation model (dem) approximation, are used in synthetic aperture radar (sar) motion compensation procedures. they usually introduce residual motion compensation errors for airborne single-antenna sar imaging and sar interferometry. in this paper, we investigate the effects of residual uncompensated motion errors, which are caused by the above two approximations, on the performance of airborne along-track interferometric sar (ati-sar). the residual uncompensated errors caused by center-beam approximation in the absence and in the presence of elevation errors are derived, respectively. airborne simulation parameters are used to verify the correctness of the analysis and to show the impacts of residual uncompensated errors on the interferometric phase errors for ati-sar. it is shown that the interferometric phase errors caused by the center-beam approximation with an accurate dem could be neglected, while the interferometric phase errors caused by the center-beam approximation with an inaccurate dem cannot be neglected when the elevation errors exceed a threshold. this research provides theoretical bases for the error source analysis and signal processing of airborne ati-sar. |
