Abstract: A study of millimeter wave stealth technology is implemented to improve ground target’s survivability in future battlefield under the threat of detection and guidance by passive millimeter wave. After considering the disadvantage of passive stealth, a new active stealth method is put forward based on the radiation characters of the target and background, then, the theory of stealth method is analyzed, and the jamming power area density of different background under a typical bandwidth is obtained after the modeling calculation is processed. Finally, The stealth characteristics of the target are tested by outfield experiments, the data shows that the radiant difference between the target and background is obvious depressed after jamming, and the technical feasibility of the stealth is also verified.

Key words: stealth technology, terminal sensitive projectile, millimeter radiometer, active stealth
