LOW-OBSERVABLE RADOMES COMPOSED OF ARAMID/EPOXY COMPOSITE SANDWICH STRUCTURES AND FREQUENCY SELECTIVE SURFACE

摘要

Radar antennas are indispensable for improving the performance of weapon systems such as aircrafts, warships and missiles. The radome (radar + dome) is a protective cover of radar antennas as shown in Fig.1. In order to shield radar antennas, the radome should be not only mechanically strong but transparent at the operational frequency range of the radar antenna.
