“…The Doppler ambiguities do not occur since the cross-track velocities of moving targets are less than 25 m/s, which is the maximum baseband velocity. Figure 8a,b demonstrates the clutter and target spectra before and after clutter suppression, respectively, where clutter suppression is realized by using the EFA method [43][44][45]. From these figures, after clutter reduction, the moving targets are visible, but they are blurred because of the RCM and DFM.…”

“…Interferometric synthetic aperture radar (InSAR), as we all know, is an advanced remote sensing method in surface measurement (Xu et al., 2020). Compared with the traditional surface measurement methods, it has the characteristics of high precision, wide coverage and basically unaffected by weather conditions (Ramirez et al., 2020).…”

“…The fundamental InSAR technique is to interfere two SAR images to obtain an interferogram (Moreira et al., 2013), which has the difference in phase between the two images from almost the same places (Xu et al., 2020). “Interfere” here means conjugate multiplication of the SLC (single look complex) data obtained by SAR satellite containing amplitude and phase information.…”

“…Different from the spaceborne synthetic aperture radar (SAR) [1][2][3][4][5][6], airborne SAR is frequently affected by atmospheric turbulence, and thus, its flight trajectory may deviate from a pre-planned straight-line trajectory [7][8][9][10]. Therefore, combining motion compensation (MoCo)/autofocus processing for airborne SAR imaging [11][12][13][14] is necessary.…”
