radar head 中文意思是什麼
radar head
解釋
雷達導引頭-
Advantages, disadvantages and limits of arm are thoroughly examined using signal processing methods. based on the above, incoherent and coherent two - point - source decoy methods and modified coherent two - point - source decoy methods to deflect arm are brought forward. arm ’ s homing heads are generally of mono - pulse structure, so coherent two - point - source ’ s interference resembles that to mono - pulse radar except that interference to radar belongs to far field scope, but interference to arm varies from far field to near field because relative distance drastically changes between the homing head and the two - point - source with missile ’ s homing head continually approaching the target
Arm的導引頭一般為單脈沖體制，因此，相干兩點源對導引頭的干擾類同於對單脈沖雷達的干擾，不同的是:對雷達的干擾都是遠場，而導引頭隨著導彈不斷接近目標，兩點源與導引頭的相對位置發生劇烈變化，由遠場變化到近場;導引頭天線口面上的合成場也發生了大的變化，相位波前的畸變產生干擾，這就是相干兩點源誘偏的基本思想。 -
With the development of aerospace science, especially the appearance of high speed attack weapons such as guided missile, radar is required to not only discover and track the target in further distance but also command plane and missile to head off the target
隨著空間技術的發展，特別是導彈等高速進攻性武器的出現，要求雷達能在更遠的距離上發現和跟蹤目標，並能及時指揮和引導飛機和導彈攔擊目標。 -

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。
