Abstract

Inverse synthetic aperture radar (ISAR) imaging on a turntable-tower test range permits convenient generation of high resolution two- and three-dimensional images of radar targets under controlled conditions. However, turntable ISAR images suffer zero-Doppler clutter (ZDC) artifacts not found in airborne SAR images. ISAR images formed at Georgia Tech.´s Electromagnetic Test Facility (EMTF) are used to demonstrate and compare two signal processing techniques to suppress zero-Doppler clutter while minimizing effects on the target signature. The first removes ZDC components in the data domain, whereas the second performs cancellation in the image domain.
