Abstract:
To study the properties of a new surface-type infrared decoy, the numerical dispersion model and the infrared radiance model of the plates are established. In addition, the temperature of a single plate was measured during combustion experiment, and the spatial position and infrared radiance of each plate are calculated in plate cloud by the two models respectively. Furthermore, the radar images of the plate cloud are simulated and analyzed in dependence of time and direction for single and multiple launching. The result shows that the surface-type infrared decoy can be a point source of interference when the missile is remote tracking. In the meanwhile, the plates cloud shelters the infrared characteristics of the plume and jets of aircraft when the missile is on IR imaging guidance mode. Moreover, With the analysis of the plate cloud dispersion at different intervals and the infrared radiation intensity in the case of different launching number, it can be concluded that a comfortable launching interval can maintain a continuous plate cloud, launching the decoys simultaneously increase the increment of the radiation intensity obviously, the multiple launching is an effective way to enhance the interference property of the decoy.

创新点说明:

建立了自燃箔片式面源红外干扰弹散布刚体运动模型,考虑了干扰箔片在实际作战过程中遮挡效应,更加准确的描述了箔片式面源干扰弹的红外特性与多级发射特性。

研究目的:

建立更加符合箔片式面源干扰弹的散布规律的工程计算模型,分析新型面源式红外干扰弹红外干扰特性规律,提高其干扰效能。

研究方法:

(1)采用六自由度刚体模型求解了数千个薄片的散布问题;

(2)基于自燃箔片单体燃烧试验获取了自燃箔片燃烧规律;

(3)结合薄片散布与薄片燃烧规律,考虑薄片间的遮挡效应,采用玻尔兹曼理论求解了自燃箔片式干扰弹单发和多级发射条件下的红外干扰规律;

结果:

该型自燃箔片式面源干扰弹能形成与战机辐射强度相似的红外干扰云团,干扰面积足够覆盖战机发动机与尾焰。

结论:

(1)自燃箔片式面源红外干扰能有效覆盖成像式雷达制导视场,单发干扰强度能满足红外辐射强度需求。

(2)采用0.2s的间射间隔能形成更有效的连续干扰云团,采用多发齐射方式能有效提升干扰效果,但干扰效率会随发射数量增加而大大降低。
