Analysis of automobile scattering center locations by SAR measurements

Synthetic aperture radar (SAR) is known to have the capability for a range independent high-resolution cross range processing. In this paper the SAR processing is used to localize the scattering centers of an automotive target at 24 GHz and 77 GHz at different bandwidths. Furthermore, the combination of digital beam forming (DBF) with SAR initiates the opportunity to determine the exact location of the scattering center in azimuth, height, and range.
