摘　　要：传统MTV型红外诱饵（以镁粉、聚四氟乙烯、氟橡胶为基本组分）的优点是其红外辐射总能量很高,可有效对抗传统热源寻的导引头。依靠燃烧高温产生光谱辐射的MTV诱饵,紫外波段和近红外波段辐射强度很高,红外中波段的辐射强度相对较低,而真实战斗机的紫外波段辐射强度较低,且其红外中近比一般大于1,因此,传统的MTV型诱饵无法对抗红外/紫外双色复合制导系统。根据光谱匹配原理设计制备了一种新型红外/紫外双色诱饵剂,基本组分为45%-75%的氧化剂（A1/A2）、10%-25%的燃料（B1/B2/B3）、25%-50%的含能粘合剂（C1/C2/C3）以及添加剂（D）,使用CEA软件对药剂配方的燃烧产物进行了理论计算,通过计算结果初步确定诱饵剂配方中各个组分的含量;采用SR5000光谱辐射计、Tensor37遥感红外光谱仪测试其红外光谱辐射特性,并分别从测试原理和计算方法、测试环境的差异性以及测试结果的稳定性等方面分析了两种仪器测试获得的结果存在差异性的可能原因;采用S2000光纤光谱仪测试其紫外光谱辐射特性,测试结果与通过理论计算获得的战斗机紫外辐射强度较为吻合;采用Imager IR8325中波红外热像仪测试其燃温特性,结果表明该双色诱饵剂与真实目标具有较为接近的温度特征。The advantage of traditional MTV infrared decoys which are mainly consist of magnesium,Teflon and VITON is that it emits high radiant energy,so it is an effective countermeasure to traditional seekers which seek the target by heat source.The spectral radiant intensity which generated from high temperature combustion of MTV infrared decoys in near infrared region and ultraviolet band is very high,and that in Mid-IR region is relative lower,however the radiant intensity of real jet fighter in ultraviolet band is low and the infrared radiant intensity ratio of Mid-IR to near IR band is greater than 1.Thus,the traditional MTV infrared decoys are hardly able to counter the seekers equipped with dual color combined guidance system.Based on the spectral matching principle,we designed and prepared a new infrared/ultraviolet dual color decoy which is mainly consist of oxidant（wt% 45-75）,fuel（wt% 10-25）,energetic binder（wt% 25-50）and additives.We conducted theoretical calculations on combustion products of the reagent combinations using CEA（Chemic equilibrium Application）software and initially determined the content of each component of the decoy formulation on the basis of the calculations results,then investigated the infrared radiation characteristics of decoys employing SR5000 spectrum radiometer and remote sensing interferometer spectrometer Tensor37 and analyzed the possible reasons for test results difference of the two systems separately from the test principle and calculation method,the testing environment,stability of testing results and other aspects.We studied the ultraviolet radiation characteristics of decoys using S2000 fiber optical spectrometer and the test results were consistent with the fighter ultraviolet radiant intensity which gained from theoretical calculation.We researched on the temperature characteristics of decoys by Imager IR 8325mid-infrared thermal imager and it turned out that the dual color decoy is similar to the real fighter target in temperature characteristics.The resul
