空空导弹红外成像制导系统仿真研究

围绕着红外成像空空导弹制导跟踪算法研究和评估的需要,提出了一种红外成像制导系统仿真实现的方法.方法采用空气动力学开源软件FlightGear和计算机图形学的函数库,在仿真中采用目标和导弹的六自由度模型,提供了必要的目标和导弹的动力学特性以及目标红外辐射特性.仿真系统中每个模块都可以根据自己的研究需要加载不同的算法,而且对不同的导引头设置起来很简单,有效保证导弹制导系统制导和跟踪算法的研究和调试需要.目前该系统已在某型红外成像空空导弹的制导系统跟踪算法研究中获得应用,并取得了很好的效果.

Research on Simulation of Infrared Imaging Air-to-Air Missile Guidance System

For the demand of research and evaluation of the tracking and guidance algorithm which is applied to the air-to-air missile infrared imaging guidance,the method of simulation system implementation was proposed. Using the FlightGear,the open source of aerodynamic simulation tool,and function library of computer graph,the (6 degree of freedom) 6DOF models of target and missile were taken,which could provide the necessary dynamic and radiation characteristics. In every block,different algorithms can be loaded as convenient as different configurations of seekers,which guarantees the demand of research and debug of the algorithm. This system has been applied to the tracking algorithm of one air-to-air missile infrared imaging guidance system,which has achieved ideal result.
