Abstract: |
Anti-simulation balloon decoys technology is an effective penetration means of ballistic missile in midcourse. Nuclear warhead is placed into metal balloon, so radar can’t detect it. But heat conduction occurs between nuclear warhead and balloon, the temperature difference of balloon decoys and balloon which warhead inside is produced. Therefore, nuclear warhead will be distinguished from balloon decoys by infrared detector. Aiming at this program, two difference aspects, namely, daytime attack and nighttime attack are researched in this paper. Thermal characteristic of balloon decoys which are released is analyzed theoretically. Thermal balance temperature and the time need to achieve balance temperature of balloon decoys are calculated. Temperature trend of balloon in midcourse which warhead inside is analyzed quantitatively. Various thermal effects of nuclear warhead and balloon can be eliminated basically by use of proper surface coating when attack in daytime. Active countermeasure and passive countermeasure make infrared detector can’t distinguish balloon which warhead inside from balloon decoys when attack in nighttime.
