Paper Abstract

The article presents a set of parameters used to compare the quality of synthetic aperture radar terrain images. This quality can be assessed using qualitative and quantitative indicators. Quantitative parameters include: spatial resolution, peak-sidelobe ratio (PSLR), integrated sidelobe ratio (ISLR), image contrast and its entropy. The quality of radar images is commonly evaluated by studying signals reflected from quasi-point objects (e.g. corner reflectors) located inside the imaged area. The radar image of such an object consists of a main lobe and side lobes that can be considered in the azimuthal and range direction. Therefore, spatial resolution, PSLR and ISLR can be determined separately for the azimuth and range. However, geometric distortions are usually analyzed in a qualitative way.
