Abstract: ABSTRACT The average cross-correlation coefficient (ACCC) is a traditional Doppler centroid estimation (DCE) method applied for complex radar data. Though the ACCC method is accurate enough for moving platforms with small acceleration, it cannot be… read more here.

DOI: 10.1109/lgrs.2022.3152452
Abstract: Most of the interferometric synthetic aperture radars (InSARs) operate in zero-squint or low-squint geometry. A spatial phase ramp in focused squint SAR images leads to a higher demand for coregistration, which limits the application of… read more here.

DOI: 10.1109/lgrs.2023.3254898
Abstract: High-squint multichannel synthetic aperture radar (SAR) in azimuth can overcome the constraint of minimum antenna area in the traditional single-channel classical SAR system, and thereby it would be much more flexible to achieve high-resolution and… read more here.
