Abstract :This paper reviewed t he realizatio n met hods of radar camouflage f ro m five aspect s , shaping design ,
absorbing materials , jamming , off set and microwave p ropagatio n indicating technique. Shaping design technique was analyzed for reducing radar cross sectio n and it s defect s. The developing directio n of absorbing material technique is to research new mechanism absorbing materials. Several new absorbing materials were int roduced. Finally t he paper stated t he mechanism and developing co nditio ns of jamming , off set and microwave p ropagatio n indicating technique. It is pointed out t hat various met hods must be used coordinately to realize radar stealt h effectively.
