“Pushing the Boundaries of Minimum Entropy Autofocus for SAR”
Lexington MA
AESS (Aerospace and Electronic Systems Society)
Speaker: Dr. Joshua Kantor, Senior Staff in the Airborne Radar Systems and Techniques group at MIT Lincoln Laboratory.
This talk will begin with a brief overview of synthetic aperture radar (SAR) imaging, and proceed to cover various increasingly sophisticated extensions of the minimum entropy autofocus method. These advanced autofocus methods are designed to handle motion compensation errors exceeding a range resolution cell. Motion errors of this magnitude are generally not observed in current generation SAR systems but may become relevant in future ultra-wide bandwidth SAR systems (e.g. using microwave photonics) as well as very high resolution ISAR systems where target motion is not precisely known.
