【Abstract】 The radar radome is the important component protecting the radar antenna-feeding system, which is directly covered on the surface of antenna. The protection performance of the radome has a direct impact on the reliability of the radar. The surface hydrophobic and aging resistance of the radome is particularly important. The principle of hydrophobic surface and the effect of rain deposition on the transmission loss of antenna are described. The importance of hydrophobic surface on radome is proved. The principle and importance of high weather resistance on the surface of the radome is also described briefly. The domestic and international situation, the preparation method and the application prospect of super hydrophobic and high weather resistant surface are discussed.更多还原
