Abstract :
This paper examines the modeling of synthetic aperture radar (SAR) phase histories with 2-D damped exponential models of low order. The use of a low order model is warranted when the radar returns are attributable to a small number of point scatterers. We show that the fit of the widely used damped exponential model is highly dependent on the image scene. Specifically, current high resolution methods have limited applicability due to mismatch between the assumed model and observed data
