The Design And Implementation Of Space-based Missile Detection Scene Simulation System Based On STK

To meet the demand of building a ground simulation for China’s space-based missile warning system, with the ideas and methods of object-oriented, this paper designed and implemented a space-based missile detection scene simulation systems; applies and analyses the missile active and middle exploration mission with space-based missile detection scene simulation system. The main work and results are as follows:In the aspect of math modeling about space-based missile detection scene simulation, this paper established motion characteristics model by analysis of the physical process of each object in the working process of space-based missile warning system. According to the missile plume radiation experience formula, this paper established plume radiation characteristic mathematical model. According to the radiation signal transmission from the target to space-based platform, this paper established target signal detection model. The above scene simulation mathematical model provides the mathematical foundation and implementation direction for the development of the simulation system.In the aspect of designing the simulation system of space-based missile detection scene, this paper summed up the functional simulation system needs, and formed design in scene object model, data structures, function and other aspects by the analysis of space-based missile detection missions. To complete the simulation system, this paper designed scene simulation subsystem and task analysis subsystem, respectively realized the scene establishment and analysis of the detection task; by combining the complementary function of the software, support to implement the simulation system.In the aspect of integration and application of space-based missile detection scene simulation system, by integrating and applying every module, this paper achieved the engineering application of simulation software of space-based missile detection scene simulation system. This paper designs two types of application cases and analyses with the software to meet the demand of space-based missile active period and middle period detection mission, and the results fit the expected value, with some engineering value.In this paper, the research work for the simulation realization of the space-based warning system workflow provides the demonstration platform, and simulation analysis of space-based missile detection capability provides an experimental tool, in using and engineering simulation experiment has certain use value.
