Mathematical Model of Inverse Synthetic Aperture Radar. 2. Radar Target Imaging Mode

Abstract

This paper is the second part of the work dealing with mathematical modeling of the inverse synthetic aperture radar. The possibility of obtaining radar images of targets moving by circumterrestrial orbits is shown with the help of image contrast optimization based on minimization of entropy function of image intensity. For illustration we use the object model consisting of five reflecting points. Satisfactory quality images confirm the ability of auto-focusing conditions of radar images for targets moving at distances up to 4,000 km for the given main parameters of a receiving-transmitting system.
