Robust range alignment algorithm via Hough transform in an ISAR imaging system
Thomas J. Sauer, Arno C. Schroth · IEEE Transactions on Aerospace and Electronic Systems · 1995
The inverse synthetic aperture radar (ISAR) algorithm for imaging objects moving in a straight line requires range alignment as a preprocessing step since scatterers migrate through the various range bins. The conventional correlation alignment method fails when applied in ground scenarios like an airport due to the clutter environment. A procedure using Hough Transform (HT) alignment is presented which overcomes this disadvantage and provides information for clutter elimination.>
