Abstract
Designing and creating invisible samples of military equipment is important modern science and technical problem. Physically, this is equivalent to reducing the object RCS. It requires fast and accurate tools (experimental or theoretical ones) to determine the RCS of different objects to which various means of reducing visibility are applied. The experimental studies require a lot of time and money, also it provides incomplete information about the object. So, it is important to create numerical effective and physically justified method for the theoretical determining of the complex shape objects RCS. There are well known numerical methods such as SBR. However, in this method there is no suitable approach for effective coating calculating, in particular such coating as a tent. The main goal of this paper is proposing a new method for taking into account some coating that is used for the object masking. To improve the accuracy of such modeling, it is necessary to use a large number of facets. Thus, recalculation of the set of parameters for the coating becomes also a difficult and time-consuming task. Therefore, it is important to develop a method for quickly assessing the effect of the certain coating parameters on the object RCS.
