  1. The result shows that the solar radiation pressure moments play a mainly part. based on kalman filtering, three kinds of attitude determination algorithms were studied using the attitude sensor now available on the explorer : the first based on digital solar sensor ( dss ) and gyroscope when the star sensor is not available ; another based on dss, high - gain antenna ( hga ) and gyroscope when the explorer is in the earth - safe mode ; the third based on star sensor combined with gyroscope when the explorer is in the normal mode

    針對配置了典型量敏感器的深空探器,基於擴展kalman濾波給出了其姿態確定的方法:針對星敏感器不可用情形,給出了使用太陽敏感器和率陀螺定姿的濾波器演算法;針對安全模式下的對地穩定定情形,給出了太陽敏感器和高增益天融合率陀螺信息的定姿演算法;針對正常巡模式給出星敏感器和率陀螺聯合定姿演算法。
  2. This system employed a new concept for measuring upper winds, viz. use of vlf very low frequency in the range of 10 - 13 khz signals from a global navigational network, omega, for computing the wind

    與以往無電相比,該系統在風方面則採用了一種新的概念,利用世界性奧米茄導站網的甚低頻信號10 - 13khz來計算出高空風和風,無需用雷達追蹤探空儀位置。
  3. Measurement of pressure, temperature and humidity operated in much the same principle as the older version of radiosonde, but computation of wind was made use of the vlf ( very low frequency in the range of 10 - 13 khz ) signals of a world - wide navigational network, omega

    該系統量度高空氣壓、氣溫及濕度的方法與舊式無電探空儀大致相同,但在風方面則採用了一種新的概念,利用世界性奧米茄導站網的甚低頻信號( 10 - 13khz )來計算出高空風和風,無需用雷達追蹤探空儀位置。
  4. During this paper, definition of the measure enter - cover - probability is given, andthree - dimension detection space are transformed to level detection circles on differentheights. aiming at the most normal situation of symmetric line, cross - to line and cross - awayline taken by the carrier, probablely - enter - cover - target - distribution are analysed in relativemovement method on the premise that targets fly perpendicular to the flying direction of thecarrier. mont - cario method is used to simulate uniformly - distributed - targets situation and getthe measure, and results are used to analyse the influence of line - landscape - orientation - ratio, line - portrait - ratio, and speed - ratio on the measure. for further research, influences of height and blind space are also discussed on base ofradar level detection range, and situations of non - uniformly - distributed targets are alsoresearched

    為了分析主動探空間動態性能,本文首先提出以「目標進入雷達覆蓋區概率」 (簡稱為「覆蓋率」 )作為評價指標;然後將三維探空間轉換為不同高度層對應的水平探圓,針對載機採用雙平行、交叉相和交叉同的最一般情形,採用相對運動的方法,分析目標垂直入侵時可能進入雷達覆蓋區的目標分佈情況;再運用蒙特卡洛法進行模擬計算,分析並比較目標服從均勻分佈時橫比、縱比及度比對性能的影響。
