屏蔽实验 meaning in English

screening experiment

Firstly , this paper summarizes modern weaponry stealth technology at home and abroad , and lays special emphasis on analyzing stealth problem of cruise missile ’ s guidance head cover , aerocraft radar canopy and other privileged sites . secondly it makes a research on related theories of transparent metallic mesh that applied to missile ’ s guidance head cover and aerocraft radar canopy , and deduces relational expression between transparent metallic mesh structural parameters and radar wave - shielding efficiency , infrared transmitting . we use laser direct writing technique to fabricate a metallic mesh ( dimension : 70mm 70mm ; line width : 5 m ; period : 350 m ) on glass surface , then do experiment to test radar wave - shielding of metallic mesh via radar transmitting and receiving device
本文首先综述了国内外现代武器系统隐身技术方法;重点对巡航导弹导引头罩和飞机雷达舱罩等特殊部位的隐身问题进行了研究,研究了金属网栅用于导弹头罩和飞机雷达舱罩隐身的相关理论,推导了金属网栅结构参数对雷达波屏蔽效率和透红外关系式;用激光直写工艺,在玻璃表面上制作了一块面积为70mm 70mm ,线宽为5 m ,线周期为350 m的金属网栅;在实验室里用雷达发射和接收装置测试了网栅对雷达波的屏蔽实验;认为利用金属网栅技术对雷达波具有一定的屏蔽作用,而且不影响精确制导的红外线高效透过。
