雷达隐身吸波材料应用研究进展及发展趋势OA

Microwave absorbing materials(MAM),as a crucial component of radar stealth technology,reduce the radar cross-section of detected targets by absorbing radar waves,thereby lowering the probability of detection.Currently widely applied in the stealth design of various aircraft,naval vessels,and armored vehicles,they effectively enhance equipment survivability and combat effectiveness on the battlefield,making them strategic key materials in the defense sector.Therefore,developing high-performance radar-absorbing materials represents both a research hotspot in advanced materials science and a critical requirement for national defense security.This paper first provides a detailed discussion on the definition,classification,and absorption principles of radar-absorbing materials.It then systematically summarizes the current research status and latest advancements across different types of radar-absorbing materials,analyzing their respective advantages and limitations based on practical application contexts.Finally,focusing on key challenges in the field,it identifies some primary future research directions:deepening the understanding of loss mechanisms,developing novel materials with unique electromagnetic responses,and enhancing engineering design capabilities.
