A Novel Motion Compensation Framework for Micro UAV FMCW SAR

F Zhang, S Yan, Y Fu, W Yang… - 2023 IEEE 16th …, 2023 - ieeexplore.ieee.org
Micro UAV gives easily rise to motion error with low amplitude and high frequency. In Micro
UAV SAR imaging, the motion error is always 2-D space variant. The high frequency motion …

An autofocus framework based on combination of parametric and nonparametric methods for stripmap SAR

F Zhang, Y Fu, W Yang, W Zhang, R Yu, S Yan - 2023 - IET
The autofocus algorithm is crucial in SAR imaging. However, it always become difficult when
phase error reflects two-dimensional space-variance property. In this paper, a robust two …
