摘要
为了对抗目前广泛应用的红外双色(1~3和3~5 μm)制导系统, 设计制备了一种能够模拟真实目标红外双波段辐射特性的新型红外双色诱饵剂, 采用Imager IR8325中波红外热像仪测试其燃烧过程中的温度变化情况以及特定时刻的火焰温度分布; 采用SR5000光谱辐射计、 Tensor37遥感红外光谱仪测试红外双色诱饵剂静态光谱辐射特性, 获得了其频域和时域特性, 分析了双色诱饵剂辐射强度和红外中近颜色比的影响因素; 同时为了研究高速飞行状态下双色诱饵剂的辐射强度和颜色比变化规律, 采用直路式等速负压气溶胶风洞进行了诱饵剂动态辐射强度测试, 解释了红外双色诱饵剂辐射特性在高速气流影响下与传统诱饵剂不同的衰减机理。 实验结果表明, 该双色诱饵剂火焰温度在850~1 100 ℃之间, 与真实目标具有较为接近的温度特征, 该诱饵剂的红外中近比为1
Abstract
In order to counter infrared dual color (1~3, 3~5 μm) guide system that is widely applied nowdays, one type of new infrared dual color decoy wihich can simulate infrared dual waveband radiation characteristics was designed and prepared in this paper. Image IR8325 infrared thermal imaging system was employed to investigate the flame temperature variation and temperture distribution of decoys. In order to analyze the influencing factor of radiation intensity and dual color ratio of the decoy, SR5000 spectrum radiometer and remote sensing interferometer spectrometer Tensor37 were adopted to investigate static infrared radiation characteristics of dual color decoys and gained its time-domain and frequency-domain characteristic. For the sake of studying the change laws of radiation intensity and dual color ratio of dual decoy which is under high speed flight station, the combustion wind tunnel was employed to investigate the dynamic radiation characteristic and it indicated the different attenuation mechanism of the dual color decoy between the traditional decoys. The test results indicates that the flame temperatue of the dual color infrared decoy temperature is between 850~1 100 ℃ and it is approximately similar to that of the plane target. The color ratio of infrared radiant intensity is from 1 to 3(1
