飞机成像目标的红外隐身效果评估

评估飞机成像目标的红外隐身效果，对飞机红外隐身技术的发展、隐身反隐身作战具有重要的意义。提出了一种飞机成像目标红外隐身效果的评估方法:结合成像探测器工作原理，考虑图像处理各个阶段的算法特点，基于多种图像特征，制定出能反映背景影响和诱饵干扰影响的飞机成像目标红外隐身效果评估指标；通过建立红外成像探测器仿真模型，验证了所制定的评估指标的合理性；最后依据评估指标评估了采用不同隐身技术和施放诱饵干扰对飞机隐身效果的影响，得到了一些对飞机隐身和反隐身具有指导意义的结论。

Infrared stealth effectiveness evaluation of aircraft imaging target

Evaluation of infrared stealth effectiveness of aircraft imaging targets was important for the development of aircraft's infrared stealth technology and operations of stealth and anti-stealth. An evaluation method for infrared stealth effect of aircraft imaging target was proposed, which was based on the principles of imaging detector and the characteristics of each stage of image processing. The evaluation indexes of aircraft's infrared stealth effectiveness as imaging target which can reflect the influence of background and decoy jamming were established based on multiple infrared image features. Then, the simulation model of infrared imaging detector was established, and the rationality of the evaluation indexes was verified. Finally, based on the evaluation indicators, the effectiveness of different stealth techniques and the application of decoy jamming on the stealth effectiveness of the aircraft were evaluated. The results have instructive meanings for aircraft's infrared stealth and anti-stealth.
