  3. Considering the fact that the analog system is not so good as the digital system on the respect of variation of bandwidths and on the respect of switch between different bandwidths. this paper proposes to adopt the dds ( direct digital synthesis ) technique that produces chirp signals of different bandwidths to improve the situation of losing tracks for the ocean satellite altitude indicator in measuring coarse surfaces

    現在的雷達基本上採用模擬系統產生線性調頻信號，由於模擬系統在帶寬變化方面和不同帶寬間切換方面不如數字系統，本文採用dds （ directdigitalsynthesis ）技術產生不同帶寬的線性調頻信號以改善海洋衛星高度計在測量粗糙表面時存在的失鎖現象。
  4. The attack is believe to have occurred as the weather satellite flew at 530 mi. altitude 4 deg. west of xichang located in sichuan province

    據信該衛星是在530英里軌道高度，西昌以西4度的地點飛行。
  5. Some 250 commercial and military satellites now orbit in the lowest altitudes, according to the satellite industry association, and most of them are defenseless against the radiation that would be released by a high - altitude atomic burst

    數目不斷增加的人造衛星為我們提供通訊、導航、無線與有線電視，以及地面攝影與天氣預報等服務。
  6.

    本文介紹了一種利用車載慣性導航設備和gps導航衛星進行車輛實時定位的導航系統，該導航儀用於實時測量車輛的經緯度、高度等數據信息，並顯示在外掛的tft液晶屏上。
  7. Several topics on coding and modulation theories of uav communication were discussed in this thesis. by analyzing features of uav communication, difference on three aspect between uav and satellite / civil mobile communication were pointed out, i. e. rapidity of the channel state parameters changing when low - altitude flying, wide range of the signal to noise ratio ( snr ) in receiver, and demand on transmission delay

    無人機通信與衛星通信、移動通信有相似之處，也有明顯不同，主要是：無人機低空飛行時通道參數變化劇烈，通信中接收機信噪比變化范圍大，要求傳輸時延短。
