采用可重构结构型吸波材料的天线RCS减缩方法
Antenna radar cross section reduction by a reconfigurable radar absorbing structure
摘要
Abstract
An active reconfigurable Radar absorbing structure using a pin diode for the radar cross section (RCS) reduction of the antenna reflector is proposed, which is able to be switched between metal reflector with OFF-state diodes and absorber with ON-state diodes.The reflection coefficient of the RAS reflector is able to be switched between less than-25.0dB with OFF-state diodes and more than-0.8dB with ON-state diodes around 8.3GHz.The RAS reflector with ON-state diodes is applied to a dipole antenna reflector and gives radiation performance equivalent to that of the dipole with a metal reflector.The RAS reflector with OFF-state diodes is used as a radar absorber for RCS reduction.Meanwhile, a chessboard-like geometry RAS reflector is proposed in response to the wideband RCS reduction.The RCS reduction band covers the working band and is extended to 5~18GHz.The results show that the reconfigurable RAS reflector can contribute to the antenna RCS reduction at the working frequency, with the radiation performance of the dipole antenna preserved.关键词
