Missiles with stealth ability will be a trend for the missiles in the future and how to develop the missiles with stealth ability has been the research subject to which more attention are paid by many countries.In this paper,anti-radar stealth and anti-infrared stealth,the main technologies for missiles to implement stealth are described in brief.For missiles,the design of their shape and the use of wave absorption material are the key technologies against radars,and the infrared supression of their engines and the use of infrared material are the key technologies against infrared detectors.Finally,the current status and trend of missiles are analyzed.
