Abstract:

A method for obtaining radar portraits of simple-shaped objects using ISAR with SFCW radar is demonstrated. An experimental setup was assembled in a large anechoic chamber of PJSC "Radiofizika" and radar portraits of objects of a simple shape were obtained: a metal cone and a cylinder.

The considered method can be used in practice for verification of radar portraits of objects, for assessing the radar visibility of objects, and also for estimating the relative contribution of various elements on the surface of an object to the resulting radar portrait.
