Presented in this paper is architecture of a simulation system for the military engagement. The architecture proposed in this paper is for the construction of a simulation system based on agent simulation design methodology. Every entity of the proposed architecture is defined of assemblage of modularized agent components, and it enhances the reusability and composability of the entity. Consequently, time, costs, and efforts that are required to develop a new simulation system are able to be reduced by the improved entity modeling methodology of the architecture. In the case of the military engagement simulation, reflection of environmental effects to simulation entities is very important, because real battle entities are operating in the battlefield of which cannot be controlled by operators. The proposed architecture contains the synthetic battlefield to simulate interaction between the environment and simulation entities. Thus, each behavior of simulation entities is changeable by the effects, and it can derive more precise results that well-represent real system operation. In conclusion, the proposed architecture supports swift construction of various engagement simulation systems that are based on the synthetic battlefield. The architecture of this paper is implemented to construct an example system for verification of the advantages.

Product systems are quickly and frequently changed because product life cycle is continuously reduced and adopting new product is steadily fast. Thus, various studies are progressed using PLC simulation which is one of control level simulation. The research that is concerning simulation of control verification for shortening the commissioning which has a lot of trial and error is in progress. Also, simulation of control verification has strength that it can catch the errors in advance. However, a virtual device in simulation needs both physical and logical model for representation of control information. For this reason, excessive time and energy is put into constructing virtual models. So, in this paper, we proposed the template model approach for the PLC simulation to cope with this problem. The proposed template model approach provides an efficient construction method for a virtual model based on control information, extracted from the test run procedure of the PLC program. We can minimize the set up time of the PLC simulation environment, as well as cut process time down using our suggestion.

A sidelobe suppression filter is designed to operate simultaneously with a matched filter. For the purpose of the design, a filter is canonically decomposed into two orthogonal components. One is the conventional matched filter, the other is the sidelobe suppression filter. The minimax optimization technique is utilized to determine the optimal filter weights to minimize the peak sidelobe level of the combined filter output. The technique is also applied to design a close-in sidelobe-free filter. The sidelobe performance of the proposed filter is compared with those of the MMSE inverse filter and the matched filter. The loss in processing gain compared with a matched filter and the filtering complexity are also examined.
