Test of Infrared Radiation Characteristics of Aircraft and Study on Launch Strategy for Infrared Decoy Flare

This study aims to investigate the infrared radiation characteristics of aircraft and provide a reference for the launch strategy for infrared decoy flares. A spectral radiometer, middle infrared thermal imager, and far infrared thermal imager were used to test the static infrared radiation performance of an aircraft. Three test points were selected: the head, positive side, and tail. The test results showed the following: (1) at the radiation intensity and radiation area of the head were the smallest; (2) the infrared radiation intensity of the tail was the largest; (3)the radiation area of the tail was small; (4) the infrared radiation area of the positive side was the largest; and (5) the radiation intensity of the positive side was large. Based on to the test results, the strategy for infrared decoy flares was analyzed. Multi-point and area infrared decoy flares are used for stern attacks; area infrared decoy flares are used for lateral attacks; and multi-point and area infrared decoy flares are used for head-on attacks.
