Effects of local peak detection on attributed scattering centre extraction in SAR

Attributed scattering centres in synthetic aperture radar imagery reveal information that would otherwise be unknown to an analyst. How the method used for pixel qualification affects the attribution is considered. Using the well-known Prony method as the standard, the effects of position estimation from local peak detection and the two-dimensional (2D) Prony method on pixel attribution to canonical scattering centres are shown. The efficacy of using 3D attributed scattering centres to characterise a commercial vehicle is also demonstrated.
