Abstract

The objects of study are wideband radar systems centimeter waves used to generate high resolution radar images of objects. The purpose of the radar under consideration is the recognition of ground and air targets. The paper discusses the commonly used coherent pulsed radar with a scanning antenna and radar using the principle of inverse synthetic aperture antenna (ISAR) for processing received echo signals. The aim is to develop radar image processing algorithm using the procedure of parametric identification, which allows to evaluate the quantitative composition of multipoint target scatterers and get a portrait of this target by calculating the complex scattering coefficients and the coordinates of the point scatterers. This portrait can be used to enhance recognition, as it contains additional information about the target, its shape and size, as well as the parameters of movement.
