Research On Effects Modeling Of Warfare Factors For Radar Under Countermeasures

With the system-of-systems combat has become the basic form of information warfare, system-of-systems(SoS) combat simulation has been an effective approach for operational effecttiveness evaluation and demonstration of weapons systems. Therefore, the analysis and evaluation the effects of Factors for Radar system has all-important significance to them demonstration and tactical usage. In addition, with the scale continued to expanded, the efficiency has become a key problem in complex simulation. The paper brought the ideal of metamodeling into the radar modeling and simulation region. The key technologies and the implement methods for the effects modeling of factors based on the motivated metamodeling were studied, some framework and procedure were established and some examples was introduced. On the side, the method of radar simulation based on effects metamodel was discussed, which can effectively improve the efficiency of the system in SoS combat simulation.Firstly, the feasibility for the effects modeling of warfare factors based on the simulation data was analyzed. By general analyzing the research actualities of the modeling and simulation methodology, effects modeling method and the radar simulation technology, the requirement and the meaning of the research on effects modeling based on simulation data were confirmed.
