The work aims to verify the construction technology, mechanical properties and environmental resistance of four stealth coatings, study the applicability of the stealth coatings combined with Radar Cross Section (RCS) simulation calculation and explore the application effect of commercial stealth coatings with a radar antenna as an example to solve the problems of poor corrosion resistance, etc. of traditional stealth coatings in a service environment characterized by high humidity, intense heat, and corrosive salt spray. An overview of the recent advancements in the research of corrosion-resistant stealth coatings was made, and the corrosion resistance mechanism of the stealth coatings was analyzed. With the stealth requirements of a specific type of radar antenna as a case study, comprehensive analysis of the environmental resistance and wave absorbing of four absorbing coatings was carried out. According to the results, it is determined that W-1.0 meets the wave absorbing requirements for use among the four commercial absorbing coatings, at the cost of sacrificing thickness, while its performance in heat resistance cannot meet the requirements of engineering applications. Further improvements of stealth coatings should be made in thin and light design and environmental adaptability.
