麥格雷戈等人曾在烏干達北部遭到當地反政府武裝的襲擊，而在勝利抵達終點前，他們還克服了諸如惡劣的氣候大面積的激流險灘以及來自鱷魚的攻擊等一系列困難。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。By the use of “ radar target backscattering simulation software ” and through many flight mode and research mode experiments with the u. s. - made helicopter ah - 64 as an example, a detailed analysis of helicopter echoes ’ time, frequency domain and time - frequency distribution characteristics is made. finally, according to these features, a tentative plan to detect hovering helicopters is proposed
本文利用專門的電磁模擬軟體，以美製「阿帕奇」直升機為例，詳細分析了直升機雷達回波的時域、頻域和時頻分佈的特性，並根據這些特點提出了雷達探測武裝懸停直升機的初步方案。With its widely application in precise guided weapons, the performance of whole weapon system is sharply improved by the complementarities of active and passive radar system
主被動雷達復合制導技術在精確制導武器上的應用，充分利用主被動雷達性能互補特點，並能兼顧導引頭系統的戰術性能、設計復雜度和費用等方面的平衡，提高了武器系統的效能。分享友人
