Abstract: As a structure/ wave-transparent integral part of aerocrafts, the stealth of radome has faced with great challenge. The stealth design and realization of radome must ensure the transmitting function in the working band of radar antenna, to realize the transmit/ stealth integration function. Stealth radome is the key component of aviation weapon equipment. It plays an important role in reducing the head RCS and improving the comprehensive performance and combat effectiveness of aerocraft. The scatter properties of radome are analyzed in this paper, the merit and shortcoming of different radome stealthy approaches are summarized. The characteristics, the mechanism of stealth and the application of frequency selective surfaces, electromagnetic band-gap, plasma stealth and metamaterials in radome stealthy are emphasized introduced. The prospects of radome Stealth technology are given at last
