    游戲操作:標題畫面,點擊「 play 」字樣的圓點圖標開始游戲, 「 instruction 」查看游戲說明, 「 website 」查看製作主頁, 「 e - mail 」與作者聯。游戲進行方式相當簡單,使用鼠標控制準移動,有恐怖分子出現時將鼠標移動到他們上,按下左鍵開火即可。
  2. The algorithm of strapdown inertial navigation system is also discussed and then use the flight - track generator to give a simulation, since a closed loop feedback integrated navigation system is designed in this paper, and the output of the filter must feed back to the strapdown inertial navigation system, the analysis of the algorithm in strapdown inertial navigation system is important. the scheme to design the trajectory of gps and the simulation of gps constellation are then studied, the simulation of gps constellation is given from the calculation of vernal equinox base on the principle of celestial mechanics, this method of different from other methods given by other paper and is useful to the research of satellite navigation system. a new method to abstract noise modal in integrated navigation system is proved to be useful in practice, this method, which is given by use the principles of stochastic processes, statistics, time series analysis, and system identification, is suitable for the kalman filter in integrated navigation system

    如航跡產生器的設計,該航跡產生器是研究組合導航問題的提,從國外一些研究組合導航統的文獻中可以看出,設計這樣一個航跡產生器是非常必要的,所以本文自行設計了這樣一個統;還討論了捷聯慣性導航統中捷聯解算的方法,並進行了模擬研究,由於在本文設計的閉環反饋式組合導航統中,對捷聯慣導統的平臺誤差進行閉環控制,需要將濾波器輸出的校正量反饋到捷聯解算內部,所以必須對捷聯解算進行深入的研究和分析,更何況捷聯解算問題本也是導航界的一個熱門研究課題;另外,本文還介紹了gps軌道及其座模擬的設計思想和方案,與以往gps軌道和座模擬不同的是本文從天體力學中計算春分點開始,逐步進行gps軌道及其座模擬,這樣的設計方法對從事衛導航的研究工作是有價值的;還對組合導航中誤差建模方法進行了研究,綜合運用隨機過程、概率統計、時序分析及統辯識等方面的理論提出了一套適合組合導航卡爾曼濾波的誤差建模方法,並運用實際研究工作中的測量數據對該方法進行了驗證。
  3. The far - distance targets can be detected with the aid of the satellite image and the ample respond time of the defensive system can be provided ; the cryptic cruise missile and anti - radiation cruise missile can be effectively detected and tracked recur to the infrared image. radar is widely used in the cruise missile defensive system. the radar in the sky can detect the further flying cruise missile, ground based radar and coastal defense radar can track and help weapons system aim at the oncoming force cruise missile

    在目情況下,衛圖像、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,藉助于衛圖像可以在遠距離發現目標,能夠為防禦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巡航導彈和反輻射巡航導彈;雷達是在巡航導彈防禦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。
