|
摘要
针对目前用于地面或低空目标成像与识别的8~14μm波段红外探测系统云雨天气情况下的应用问题,以实验所在的地理位置为参照点,采用Pc Mod Win大气仿真软件进行了晴朗大气、云雨天气环境下的模拟实验,分析了不同条件下一定距离范围内红外辐射透过率分布曲线和峰值参数的变化规律,参考比对红外系统拍摄的目标实物图像,证明了探测角度、大气能见度、降雨强度、云层类型等,都是影响该波段红外探测系统应用效果的主要因素,提出了工程应用中应当采取的策略方法。应用实践证明,该研究结论不但具有普遍的工程意义,而且对该波段红外武器系统的作战运用也具有重要的指导作用。
Aiming at the application of the 8 ~ 12 μm band infrared detection system used for the ground or low altitude target imaging and identifying in cloud and rainy weather,taking the experiment location as the reference point,the simulated experiments are carried out for the environment of clearness atmosphere and cloud rainy weather by PcMod Win atmospheric simulation software. The distribution curves of infrared radiation transmittance and the variation law of peak parameters in a certain distance range under different conditions are analyzed. Compared with the real infrared target image,it is proved that some parameters are the main factors affecting the application effect of infrared detection system in this band,such as the detection angle,atmospheric visibility,rainfall intensity,cloud type,etc.,and the strategy methods are put forward which should be taken in engineering application. Application results show that the conclusion of the research has general engineering significance,and plays an important role in the war application of the infrared weapon system in this band.
