  1. The pseudo - random fsk / psk multi - modulation signal and the partly - matched processing signal remain the information of the target of interest. compared with the other processing methods, the partly - matched procession could depict the target ' s information effectively, and could get a higher output snr under a noisy environment. in this dissertation, the deduction and the simulink on the computer of the average ambiguity function of the pseudo - random fsk / psk multi - modulation signal are presented. also, to the partly - matched procession, analysis in theory and simulink on computer are presented. the partly - matched procession applied in radar field is also discussed

    較其它處理方法，非完全匹配處理能有效的突出所觀測目標的信息，以及在加噪情況下，其具有高的輸出信噪比。在論文中，對偽隨機fsk / psk復合調制信號的模糊特性進行了推導與模擬，對非完全匹配處理方法進行了理論上的分析以及計算機上的模擬驗證，討論了其在雷達中的應用。
  2. 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。
