The design and construction of any complex information and control systems, including complex radar systems (CRSs), involve a long-term multistage process. The most important stage of CRS development is the design. Therefore, an essential development carried out simultaneously with a reduction in lead time is an important issue of the day. The solution of this problem is based on designing and widespread occurrence of science-based methods of system development taking into consideration structural features of systems and conditions of functioning that are founded on widely used computer subsystems.
