Abstract
This correspondence shows that resonance signatures
in ultra-wideband synthetic aperture radar (SAR) images, which are
smeared out due to their late arrival time, can be focused and extracted by
postfiltering the SAR images with special two-dimensional (2-D) allpass
filters. A design algorithm for FIR approximations to the desired allpass
filters based on radial slice approximations (RSA) is presented.
Keywords
radial slice approximation , Allpass filters , resonance signatures , synthetic aperture radar.
