Abstract :
Synthetic Aperture Radar (SAR) image quality parameters attained from the images are always different from system specification in resolution and side lobe intensity. It is difficult to locate effective point targets for calculating of SAR image quality parameters of impulse response function (IRF) characterization. In this paper, an objective image quality assessment method is proposed based on image region information. Spatial resolution (SR), peak side lobe ratio (PSLR) and integrated side lobe ratio (ISLR) are calculated using the coherent correlation function (CCF) of complex SAR images.
