We introduce from first principles a synthetic aperture radar (SAR) imaging and target motion estimation method that is combined with compensation for radar platform trajectory perturbations. The main steps of the method are (a) segmentation of the data into properly calibrated small apertures, (b) motion or platform trajectory perturbation estimation using the Wigner transform and the ambiguity function of the data in a complementary way and (c) combination of small aperture estimates and… 
Motion Estimation and Imaging of Complex Scenes with Synthetic Aperture Radar
TLDR
The robust PCA method is designed to separate the low rank from the sparse part, and thus can be used for the SAR data separation, and how they can be combined to improve the data separation for extended and complex imaging scenes is explained.
Synthetic Aperture Radar Imaging and Motion Estimation via Robust Principal Component Analysis
TLDR
It is shown that the robust principal component analysis (PCA) method which decomposes a matrix into two parts, one low rank and one sparse, can be used for motion detection and data separation.
