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。 Aiming at the need of research and evaluation of guidance imaging tracking algorithm of infrared imaging air-to-air missile, a simulation method of infrared imaging guidance system is proposed. Methods The library of FlightGear and Computer Graphics, which is a kind of open-source aerodynamic software, is used. The six DOF model of the target and the missile is used in the simulation, which provides the necessary targets and missile dynamics as well as the target infrared radiation characteristics. Each module in the simulation system can load different algorithms according to its own research needs, and it is easy to set up for different seeker, so as to effectively guarantee the research and debugging of missile guidance and tracking algorithms. At present, the system has been applied in the tracking algorithm of guidance system of a certain type of infrared imaging air-to-air missile, and has achieved good results.
