Based on mono - pulse radar system and the analysis of terrain echoes, a geometrical model of air to ground ranging is constituted. by using the signals received from the sum and difference channels of terrain follow radar, a group of the expressions for terrain echoes are educed and characteristics of these echoes are obtained. according to the characteristics of the echoes, the theory and method of pass zero detection of difference channel and its applications are discussed in detail
針對一維單脈沖雷達體制,分析了地形目標回波特性;建立了地形跟隨雷達空地測距的幾何關系;利用雷達收發信號,導出了地形跟隨雷達和差接收通道的回波信號表達式,進行了波形模擬,得到了地形跟隨雷達的地面散射產生回波在時域中的特性;根據和差回波特性,闡述了差信號過零點檢測測距的原理和方法及工程實踐中的應用,並給出了真實雷達對外輻射試驗的結果,驗證了文中的模擬。The successful launch and return of shenzhou - vi, marks that our aerospace technology has entered the era of large - scale near - space exploitation and utilization. in the near future, the technology is directly expected to serve for national economy. in order to develop the space experiment and research on its application, it is imperative to build a permanent space station., where rendezvous and docking plays an important role. meanwhile, the technology of the rendezvous lidar is pivotal for rendezvous and docking
神六的成功發射和返回,標志著我國的航天事業進入了大規模開發和利用近地空間的新階段。為了開展空間科學試驗和應用技術研究,就必須建設永久性空間站。空間交會對接技術是建立空間站的關鍵技術,而空間交會激光雷達技術又是空間交會中的關鍵技術。This paper introduces the launching, levitating and injecting situation of american iridium satellite ( double satellite ), " long - march 4b " one rocket and two satellites, " shanzhou no. 1 " experimental satellite, " zhongxing 22 " communication satellite, and the first " resource no. 2 " satellite, etc
介紹了美國銥星(雙星) 、 「長四乙」一箭雙星、 「神舟一號」試驗飛船、 「中星22 」通信衛星、第一顆「資源二號」衛星等的發射、升空和入軌情況。The research of this paper includes : ? high - speed photography and flash x - ray radiography are both used to capture the process of al shell ' s great deformation under low pressure. front illuminations are used to get the development of the fracture on the al shell. the relative energy release is analyzed from overpressure curves measured with some sensors
本文的研究內容主要包括: ?在受試炸藥經歷低應力大變形過程的susan試驗中,同時採用高速攝影、閃光x射線照相對彈體的撞靶過程進行了拍攝,得到了殼體膨脹變形過程圖像,並使用前照明技術觀察到了鋁殼表面產生的裂紋及其發展變化過程;從壓力傳感器測量的空氣沖擊波超壓曲線,獲得反應釋放總能。In large rotating machinery using filmatic bearing ( turbogenerator, air compressor, etc. ) there is a potential trouble from impefect installation or running conditions, a metals " contact between rotors and shells. the trouble is usully called rubbing. the advantage of ae technologe in the rubbing diagnosis and early detection is showed. instead of classical ae characteristic parameters ( counts, amplitude, energy, duration and the other ones ) a new feature extraction by frequency analysis of ae envelop signals is discussed. both research of ae process and field experements indicate that periodic components in the envelop spectrum related to rotational speed increase evidently at the beginning of rubbing production, hence are highly sensitive to the rubbing fault diagnosis. according to the new design an acoustic emission equipment for the rubbing diagnosis named buaa ae testing system is developed and described
汽輪發電機、空氣壓縮機等採用油膜支撐的大型轉動機械,由於安裝或運行中的原因,在轉子旋轉過程中,可能和器壁發生輕微的摩擦和碰擊,簡稱碰摩.聲發射技術在碰摩發生特別是故障早期診斷上有優越性.本系統的特點是沒有沿用傳統的計數、幅度、能量和持續時間等聲發射特性參數,而是在聲發射包絡信號的頻率分析中進行特徵提取.聲發射發生的過程分析和現場試驗都表明這種方法對碰摩檢測很敏感,在碰摩發生的起始階段,包絡譜中與轉速同步的周期性分量顯著增加.根據這種新的設計思想自行研製了buaa碰摩聲發射檢測儀並對此作了介紹In course of image enhancement processing, this paper, by the means of radiation enhancement, spatial enhancement, image operation, color enhancement and rs data merge, thinks that the combined image by textural information image and original image can reflect both detail information and textural information while carrying out non - directional edge of the linear stretch image
在圖像增強處理中,運用輻射增強、空間增強、圖像運算、色彩增強、多源遙感數據融合等多種方法,經過多次試驗對比,發現對線性拉伸后的圖像進行非定向邊緣增強,得到的紋理信息圖像再與原始圖像作疊加運算,得到的合成圖像既突出了圖像的細節信息又突出了紋理信息。分享友人
