| Abstract: Various technologies for mitigating distortion in coherent image products
generated from SAR data are described herein. Synthetic aperture radar
(SAR) datasets generated based upon SAR returns from first and second
passes of a SAR platform over a scene are received. The SAR datasets can
be co-notched at matching sample indices to improve coherence of SAR
images generated from the datasets. Windowed SAR data is generated by
applying independent windows to subsets of each of the datasets to reduce
sidelobe levels of their image impulse responses. Coherent image products
are generated based upon the windowed SAR data, wherein an image quality
of the coherent image products is improved as compared to coherent image
products generated based upon the SAR datasets. |
