Development Of Virtual Test System For Radar Guided Missile Based On Informatization Architecture

The operation of various weapon equipment needs a certain natural environment, therefore, as the main component of the natural environment, the atmosphere environment plays important role on the weapon equipment. In order to carry out the missile test in various environments more convenient, the experiment of the weapon equipment in the complicated atmosphere environment is realized by the method of virtual experiment. The task of this thesis is to construct the virtual radar guided missile test system and realize the effectiven ess evaluation of radar guided missile under different weather conditions based on the general virtual test architecture--information architecture platform.In order to improve the support of the platform for virtual missile test, simulate the construction of real system, as well to provide the reusability and flexibility of electromagnetic wave transmission calculation function, divide the system to electromagnetic wave transmission effect component, virtual radar guided missile component and virtual ship component, which is different from the past of coupling test system. All the components are independent in function, and they can have information interaction in the virtual test system.In order to construct the test system, this thesis have researched and modeled the effect of electromagnetic wave propagation, virtual radar guided missiles and virtual ship. As the bridge of information interaction in the test system and the key part, electromagnetic wave transmission effect model support the electromagnetic wave propagation attenuation calculation of ideal space, sunny environment, fog environment, rain and snow environment. This model achieved the requirements of precision and efficiency through improving the adaptability of the classical theory of electromagnetic transmission. The Describe Word Pulse(PDW) is selected as the pulse signal of missile borne radar, and radar can get precise location of the target by the rich information of the model. The virtual missile and virtual ship models are open functional level simulation model, they both have electromagnetic characteristics and motion characteristics.Accomplished the demand analysis of the components required by the virtual test system based on the mathematical mode, calculate the transmission attenuation according to the choice of the atmospheric environment, when electromagnetic wave transmission effect component receive the electromagnetic wave transmitted by other components, and then sent to the corresponding component. Using UML(Unified Modeling Language) to describe the design and development process of the various components, and to analyze the key points and difficulties in details, based on the above. Finally, completed component design and development in the QT and visual studio platform, and built a radar guided missile virtual test system.After testing, the model, each component and the whole system can meet both of the function requirements and real-time requirements.
