SURVEY OF RADAR STEALTH TECHNOLOGY

This paper reviewed the realization methods of radar camouflage from five aspects, shaping design, absorbing materials, jamming, offset and microwave propagation indicating technique. Shaping design technique was analyzed for reducing radar cross section and its defects. The developing direction of absorbing material technique is to research new mechanism absorbing materials. Several new absorbing materials were introduced. Finally the paper stated the mechanism and developing conditions of jamming, offset and microwave propagation indicating technique. It is pointed out that various methods must be used coordinately to realize radar stealth effectively.
