首先，在闡述i / q正交調制基本原理的基礎上，通過對誤差矢量和鄰近通道功率泄漏的詳細分析，定性、定量地討論了各種非理想電路因素（如相位不平衡、幅度不平衡、直流偏差等）對調制器性能的影響;其次，介紹了鎖相環的工作原理和基本組成部分，包括鎖相環的設計和環路濾波器的設計，特別詳述了電荷泵鎖相頻率源;第三，介紹了採用直接調制技術模擬衛星信號的射頻前端的設計;最後，對整個直接射頻調制系統進行測試，結果基本上達到了課題要求。Some asteroids, despite their small size, possess satellites of their own. a handful of others suffer serious perturbations by major planets and travel in highly eccentric orbits, which can send them well beyond the orbit of jupiter. the so - called near - earth asteroids cross the earth s orbit and make occasional close calls to our home planet
有些小行星體積雖小，但竟然擁有衛星而有些小行星，由於受到其他大行星的強烈攝動，軌道為極狹長的橢圓，遠日點甚至延伸至木星的軌道以外近地小行星則會越過地球的軌道，不時在我們的庭園掠過，偷窺地球的一切，若有天真的登門造訪旄轟！Without any foreign assistance, china has independently developed intermediate and short - range missiles, long - range rockets, submarine - launched solid - propellant rockets, recoverable satellites, the technology to launch multiple satellites atop a single rocket, and geostationary communication satellites

空基導航系統代表有美國的gps和俄國的glonass衛星導航系統。 ncaps系統是我國科學家最近提出的一種新的衛星導航系統。其主要原理是：地面控制站利用通信衛星（而不是專用的導航衛星）轉發導航電文給接收機，接收機利用導航電文解算出本地位置。They are equipped with meteorological instruments supplied by the hong kong observatory. ship officers on board make regular weather reports and send them to nearby coastal radio stations or coast earth stations for onward transmission to meteorological centres

中國否認最近的地面反衛星導彈測試會引發國際空間武器競賽。Extreme ultraviolet radiation and x - ray created by magnetic field around the sunspots also cause the earth s atmosphere to heat up and expand. this will create additional drag to satellites or space shuttles orbiting at low altitudes and eventually pull them out of orbits earlier than expected
太陽黑子附近的磁場所產生的遠紫外輻射和x射線，使地球大氣溫度上升並且膨脹，這對在較低軌道運行的人造衛星或太空梭帶來阻力，令它們比預期提早偏離軌道。Wire antennas are still very popular on vehicles, ships and aircrafts. they are easily to be interference sources and sensitive bodies. in our calculation we must take account of the mutual coupling between wire antennas when they are very close
線天線在移動通信系統中被廣泛地應用，它作為許多機載、艦載、衛星、通信電子設備中電磁能量的發射和接收埠，最有可能成為輻射干擾的干擾源和敏感體，特別是當天線靠得很近的時候，必須考慮相互之間的互耦。Dttb ( digital television terrestrial broadcasting ) is one of the present digital television broadcasting modes, whose transmission media is earth. after a decade of intense research and development, the standards of digital television satellite broadcasting and digital television cable broadcasting have been confirmed. but the standard of digital television terrestrial broadcasting is still in disputation, for its transmission environment is rather awful, its spectrum resource is very limited and its service required is disperse, so it is potential to be improved in many aspects
數字電視廣播發展近十年來，衛星和有線電纜廣播的基本傳輸體制已確定，而地面廣播由於傳輸環境惡劣，頻譜資源有限，應用需求分散，其標準在各國仍有極大的爭議，因為目前沒有一套標準能解決實際地面傳輸中的所有問題，因此數字電視地面廣播在許多方面都有很大的改進潛力。Orbiting at several hundred kilometres aloft, these satellites are closer to the earth than geostationary ones and thus produce images of higher resolution
