Concept of Radars Synthesis Theory for Creating Phantom Objects in SAR Images

Today, for many remote sensing tasks, systems with synthetic aperture radar onboard are used. It is due to the ability to obtain images at any time of the day and in almost any weather conditions. However, sometimes there is a need to hide or replace information about existing objects in some area. Current solutions for replacing information on radar images have several disadvantages, such as long deployment time and/or requiring a large number of reflectors. The authors propose to solve these shortcomings by using active radio phantomization systems. To develop such systems, the concept theory of radio image phantomization (replacing the real one) for remote sensing systems is proposed. This paper provides the rationale for creating phantomization systems, the main idea, working hypotheses, and challenges that should be solved within the development of such a theory. The authors present the geometry of the phantomization radar application and a generalized diagram of such a radar.
