【摘要】：面源红外诱饵相比于传统的红外诱饵,在燃烧速率、扩散范围、干扰效能等方面具有显著的优越性。考虑实验成本的经济性和测试干扰效能的效率,提出了一种空战对抗中面源红外诱饵干扰效能的仿真思路。首先,建立了导弹运动和导引头跟踪模型、飞机红外辐射模型,作为空战对抗双方的假想;其次,建立了诱饵箔片的运动与燃烧模型,以诱饵箔片为研究对象,求解箔片表面温度分布,并通过燃烧算法优化,得到整体辐射特性;最后,通过改变面源诱饵的发射角度、高度、目标机速度等参数,进行干扰成功率的仿真。仿真结果表明,提出的效能评估思路可行有效,与真实测试很接近,达到面源诱饵干扰效能评估的要求。
[Abstract]:Compared with traditional infrared decoys, non-point infrared decoys have significant advantages in combustion rate, diffusion range, interference efficiency, etc. The economy of experimental cost and the efficiency of testing interference effectiveness are considered. In this paper, a simulation idea of the jamming effectiveness of non-point source infrared decoy in air combat is proposed. Firstly, the missile motion and seeker tracking model and the infrared radiation model of aircraft are established as the hypotheses of both sides of the air combat confrontation. Secondly, the motion and combustion model of the decoy chaff is established. The surface temperature distribution of the decoy foil is solved, and the overall radiation characteristic is obtained by optimizing the combustion algorithm. Finally, the jamming success rate is simulated by changing the launch angle, height and target speed of the decoy. The simulation results show that the proposed method is feasible and effective, which is very close to the real test. Meet the requirements of the effectiveness evaluation of surface source decoy interference.
