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 8325 mid-infrared thermal imager and it turned out that the dual color decoy is similar to the real fighter target in temperature characteristics.The results indicates that the infrared radiant intensity ratio of Mid-IR to near IR band is from 1 to 3(1
