Abstract: In the future complex electromagnetic environment battlefield, missile radio frequency stealth will play an important role in combat, the radio frequency stealth technology continues to be applied to missile, improving the operational effectiveness of missiles. This paper analyzes the requirement of missile radio frequency stealth, summarizes the process of missile radio frequency stealth, analyzes passive detection and missile radio frequency. The mechanism of the relevant technology is analyzed, and the strategy of how to reduce the probability of missile interception is analyzed and the improvement method is put forward, which provides a reference for improving the capability of missile RF stealth. Finally, the development of radio frequency stealth technology is briefly described.
