    間接射線法的分析步驟為:從參考面出發的入射平面波（經天線罩）在閉合面sa （在天線罩內且包圍天線）上的接收場為et 、 ht ，天線在sa上的發射場為ea 、 ha ，由洛侖茲互易定理可求出天線的遠區場。
  3. 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

    本文首先綜述了國內外現代武器系統隱身技術方法;重點對巡航導彈導引頭罩和飛機雷達艙罩等特殊部位的隱身問題進行了研究，研究了金屬網柵用於導彈頭罩和飛機雷達艙罩隱身的相關理論，推導了金屬網柵結構參數對雷達波屏蔽效率和透紅外關系式;用激光直寫工藝，在玻璃表面上製作了一塊面積為70mm 70mm ，線寬為5 m ，線周期為350 m的金屬網柵;在實驗室里用雷達發射和接收裝置測試了網柵對雷達波的屏蔽實驗;認為利用金屬網柵技術對雷達波具有一定的屏蔽作用，而且不影響精確制導的紅外線高效透過。
