自适应红外隐身系统的可行性分析

自适应红外隐身系统通过获取背景的红外辐射分布,实时改变自身的红外辐射分布从而与背景相一致。在此过程中,背景的红外辐射分布是被目标所遮挡住的背景,这部分背景随着观察点的改变而改变,如何准确地获取背景的红外辐射分布,关系到整个系统的隐身效果。本文在背景获取过程模型的基础上,结合模型参数的实际获取精度,对背景获取结果进行了误差分析,得到各参数对背景获取结果的影响,通过分析不同初始参数下的误差得到了实现完全隐身的最小距离,对比目前探测技术的作用距离,得出自适应红外隐身技术能够有效地降低被识别的概率。

Feasibility analysis of the self-adaptive infrared stealth system

The self-adaptive infrared stealth system can change the distribution of infrared radiance to be consistent with the background. In this process,the distribution of background infrared radiance is the obscured background by the object,and this part of background is changed with the viewpoint. The accurate distribution of background radiance is concern with the stealth efficient of the system. Based on the model of background radiation acquisition and the actual precision of model parameters,the error is analyzed for the results of background acquisition,and the influence of each parameter on the results is obtained. Though the error analysis in different initial conditions,a minimal distance is gotten when the object can be completely invisible. Comparing with the operating distance of infrared detector,the self-adaptive infrared stealth system can reduce the probability of being detected.
