小型化RCS增强雷达反射器设计
Design of Miniaturized Radar Reflector with RCS Enhancement
摘要
Abstract
The Radar reflector has a strong ability to reflect the incident radar wave,which has high radar cross section(RCS)and has been widely used in radar electronic defense.However,the RCS of traditional radar reflectors is generally limited by volume and difficult to miniaturize.A miniaturized radar reflector design with RCS enhancement is proposed in this paper,which can achieve larger RCS with smaller structure size.The radar reflector is based on the active Van-Atta array.The transceiver antenna array uses a magnetoelectric dipole antenna with a broadband wide beam and loads a high gain amplifier in each transceiver link,which enlarges the incident wave and reflects it back in the incident direction.An isolation module based on loss material is designed between transceiver arrays to reduce the self-excitation caused by mutual coupling.A radar reflector prototype with maximum size of 30 cm was fabricated.Its maxi-mum RCS of 10 GHz achieves 5 240 m2,larger than the maximum RCS(4 650 m2)of tri-corner reflector with a side length of 1 m.关键词
