In order to make the terminal airspace moderated and consisted, and acquire the biggest capacity of airport, we must consider the influencing factors as many as possible, it is our final target to plan the airspace in beijing terminal unify. with the conditions that the current operation modes of parallel runway, approach and departure procedures and terminal airspace in beijing international airport, this article has analyzed the reasons of airspace congestion. this article also applies the theory of instrument flight procedure and utilizes the current facilities in beijing international airport. the design of flight procedures combining rnav procedures with instrument approach procedures may be accepted on some routes. it make the approach and departure procedure more effective, and increase the capacity of the airport more or less ; secondly, this article contrast the capacities of parallel runway in different methods under radar control, and make the conclusion that the parallel runway in dependent operation modes has the biggest capacity
本文從目前首都機場平行跑道的運行方式、進離場程序、終端區空域的現狀入手,剖析了造成空域緊張的原因,應用儀表飛行程序設計的思想和原則,利用首都機場終端區現有的設施,某些航線可採用區域導航( rnav )程序與儀表進近程序相結合的飛行程序設計,優化了目前首都機場的進離場程序,在一定程度上增加了機場容量;其次,研究了雷達管制條件下平行跑道不同運行方式的容量對比,得出平行跑道獨立運行的容量最大,然後以這種這種運行方式,為首都機場設計出了平行跑道獨立運行的飛行程序;最後,分析北京終端區各機場空域對首都機場飛行程序安全、有效運行的制約因素,研究設計出了北京終端區規劃方案及規劃后的飛行程序和飛行方法,以達到增大機場的容量,適應未來航班量增加的需求。Because of its invariability, poles is the most effective characteristic signal of the radar target in resonance region

在目前情況下,衛星圖像、紅外圖像以及雷達成像在探測、跟蹤、識別、打擊巡航導彈目標方面具有相當大的優勢,藉助于衛星圖像可以在遠距離發現目標,能夠為防禦系統提供比較充足的響應時間;藉助于紅外圖像可以有效對付隱身巡航導彈和反輻射巡航導彈;雷達是在巡航導彈防禦系統中使用最多的設備,空基雷達能夠探測離防區比較遠的巡航導彈,陸基雷達和海基雷達能夠跟蹤巡航導彈,並可協助武器系統瞄準來襲巡航導彈,尤其是雷達陣在巡航導彈防禦中更是可以發揮重要作用。The international ship and port facility security ( isps ) code came into force during the year. in preparation for this, the region completed its research into the introduction of new operating protocols for maritime policing. a package of recommendations will see the integration of a technologically advanced coastal security system with digitally enhanced radar
