空-空导弹打靶专家仿真系统

AN EXPERT SIMULATION SYSTEM FOR TARGET PRACTICE OF AIR-TO-AIR MISSILES

本文介绍一个为检验空空导弹性能而研制的空空导弹打靶专家仿真系统。该系统采用专家经验选择导弹初始攻击条件和目标的逃逸策略,因而可以大大减少检验导弹性能所必需的仿真次数。该系统采用通用型数学模型,并把与具体导弹及目标有关的知识与一般性知识分开,因而具有较强的通用性。

It is a very complex and time-consuming work to evaluate the performance of the air-to-air missiles. For overcoming this difficulty, an expert simulation system for target practice of air-to-air missiles was designed recently. With the inital attack conditions and the target avoidance strategy being selected with the expert knowledge, the simulation times necessary for evaluating the performance of missiles is reduced in a great deal. The use of general mathematical models and the separation between the general knowledge and the knowledge related to certain missiles and targets make the system be able to be applied to various kinds of air-to-air missiles. This paper introduces this simulation system, including system structure, avoidance strategy analysis,knowledge representation and the building of general mathematical models. The application example of this system to a certain kind of missile is also given with the intention to demonstrate the effectiveness of the system.
