This paper discusses the necessity of realizing stealth of communication vehicles, and discusses the main technical ways of radar stealth technology, infrared stealth technology, visible light stealth technology and acoustic stealth technology, especially points out that the realization of stealth is the most effective stealth way in the design of new communication vehicles. After stealth design, communication vehicle can shorten enemy detection distance, reduce enemy target recognition ability, effectively enhance survivability, and has strong tactical significance.
