Interference Effectiveness Analysis of Infrared Imaging System Influenced by Foam

泡沫作为一种新的无源干扰手段,对红外成像系统具有长效的干扰作用。对影响泡沫干扰效能的因素进行分析,根据泡沫干扰及红外成像系统探测目标的要求,对红外成像系统的遮蔽面密度和泡沫两点间面密度进行定量计算。并利用Matlab仿真工具进行了数值仿真,仿真结果表明:随着源强、泡沫光程的增大,两点间面密度逐渐增大。通过两种面密度的比较,对泡沫的干扰效能进行分析。研究结论,对泡沫干扰效能评估及泡沫干扰战术的运用具有重要的意义。

Foam as a new method of passive interference, interference effects on infrared imaging system with long - acting. The factors of influencing foam interference effectiveness was analyzed, according to requirements of foam interference and target detection of infrared imaging system, the sheltered surface density of infrared imaging system and foam surface density between two points was calculated quantitatively. Using Matlab simulation tool for the numerical simulation, it shows that with increasing of source intensity and foam optical distance, surface density between two points is increasing. By comparison of two surface density, interference effectiveness of foam is analyzed. Following conclusion have important significance for foams interference efficiency evaluation and application of foam interference tactics.
