Study on the Infrared Radiation Signatures of Thermite

In order to discuss the infrared radiation property of thermite,six different thermites were designed and prepared,then the infrared radiation of six thermites were measured.It is found by the experiments that in 4.15～5 μm the maximum infrared radiance of Al+Fe3O4 and Mg+CuO were 66934 and 43718 W·m-2·sr-1 respectively;in 2.5～3.11 μm the maximum infrared radiance of Al+Fe3O4 and Al+CuO were 15097 and 13365 W·m-2·sr-1 respectively.Thermites also have better infrared radiation intensity in 8～14 μm,The maximum infrared radiance of Mg+Fe3O4 and Al+CuO were 691.5 and 611.8 W·m-2·sr-1 respectively.Results show that thermite is a highly efficient additive in infrared decoy.
