We come to the conclusion that shielding efficiency can be improved by increasing metallic mesh ’ s line width or reducing metallic mesh ’ s period
得出通過增加網柵的線寬和減小網柵的周期，可以提高金屬網柵對雷達波的屏蔽效率的結論。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。This paper utilizes masking rate theory to analyze the variation of center zero - level energy, the influence of metallic mesh ’ s different parameters on infrared transmitting ; deduces the relational expression between infrared transmitting efficiency and metallic mesh ’ s parameters ; comes to the conclusion that we can improve infrared transmitting efficiency by increasing
理論研究表明，金屬網柵的周期選擇在200 ~ 400 m之間，線寬不大於10 m ，是較為理想的網柵參數。最後，在實驗室里用1 ~ 20ghz的信號發生器、功率放大器和頻譜分析儀等雷達波檢測設備，對金屬網柵的屏蔽效率進行測試。The complex situation of flight requests that the graphics display of cockpit must be dynamic, real - time and legible. but in the raster graphic display system, scale lines and character will be distorted seriously owe to the limited screen resolution in the case of deflection, which affect the display quality. the thesis based on the research of the last graduate student improves the graphics creating arithmetic more and puts forward more effective arithmetic on scale lines and character for high display quality
由於飛行狀態復雜，要求座艙內畫面顯示動態、實時、清晰。而硬體系統採用的是光柵圖形顯示，字元和刻度線的旋轉受屏幕解析度的限制存在著鋸齒走樣現象，影響顯示效果。本文在上一屆研究生研究的基礎上，在圖形生成演算法上加以進一步改進，重點在刻度線、字元的反走樣處理上，研究出了更合理的演算法，提高了圖形顯示質量。This paper uses the theory of equivalent circuit and equivalent membrane to analyze the influence of metallic mesh on radar wave shielding, deduce the relational expression between shielding efficiency and metallic mesh ’ s width, period
用等效電路模型和等效膜理論，分析了金屬網柵結構參數對雷達波屏蔽作用的影響，推導出了屏蔽效率與金屬網柵周期和線寬的關系式。分享友人
