摘要/Abstract

摘要： 红外（IR）诱饵弹是一种主要的红外对抗武器，建立一种准确的红外诱饵弹模型将对红外制导算法的研究起重要作用。目前，针对红外诱饵弹的计算机流体仿真（CFD）建模方法中，通常不考虑红外药剂的燃烧对红外模型产生的影响，这将从机理上直接导致建模精度下降。针对这一不足，本文在增强型离散相模型（DPM）红外诱饵弹建模方法的基础上加入了化学燃烧相，建立了准确性更高的仿真模型。实验结果表明，与原有的模型相比，加入化学燃烧相后的新模型在图形特征的仿真精度上有明显提升。

Abstract: Infrared (IR) decoys are a main IR countermeasure weapon. Establishing an accurate model of infrared decoy missiles will play an important role in the research of infrared guidance algorithms. However, the current Computational Fluid Dynamics (CFD) model of infrared decoys does not take the influence of infrared pyrotechnics combustion into consideration, directly leading to the decline in IR decoy modeling accuracy theoretically. Aiming at this problem, this study establishes a more accurate IR decoy simulation model by adding a chemical combustion phase based on the enhanced Discrete Phase Model (DPM) IR decoy model. Results show that the simulation accuracy of graphic characteristics of the new model is obviously improved compared to the traditional one.

Key words: modeling of infrared decoys, discrete phase model, computational fluid dynamics, chemical combustion, equivalent blackbody radiation
