Motion Compensation in Post-PFA Domain for High Resolution Spotlight SAR Imagery

摘要：

A novel motion compensation (MoCo) algorithm for high resolution (HR) spotlight SAR imagery is proposed. It is capable of correcting both phase error and range cell migration (RCM) in the post-PFA data domain. It is a robust way to estimate phase error by Map-drift (MD) method, including range-invariant and range-variant ones. What is more, the random characteristic of RCM is also taken into consideration to achieve a well aligned range profile data. Finally, series experimental results are listed to validate the proposal.
