解釋
搜索天線-
The new antenna system can not only search the target very easy, but also possess the high tracking accury
新系統既容易搜索發現空中目標，又具有較高跟蹤精度。 -
The system of radar antenna controller is used to control the movement of radar antenna, which can realize to search, capture, track the targets and transfer the data of radar azimuth angle and high - low angle to computer
雷達天控器系統是用來控制雷達天線的運動，實現對目標的搜索、截獲、跟蹤，並將天線的方位角和高低角數據傳遞給計算機。 -
A multiloop antenna pointing controller has been designed while three feedforward schemes are used in this control design. the simulation results show that the antenna pointing control system can improve the precision of the attitude angle and the attitude angle rate, and the antenna can slew to the neighborhood of tdrs fast, search and then track tdrs
在設計好的天線跟蹤指向控制系統基礎上，採用前饋+反饋的復合控制策略設計了復合控制器，模擬結果表明設計的天線指向控制系統能夠較好的提高星體的姿態穩定度和控制精度，天線能夠快速回掃至中繼衛星附近並進行跟蹤，天線指向精度滿足設計要求，表明了所設計的天線指向控制系統的合理性和有效性。 -
After analyzing the existing ambiguity resolution methods the dissertation investigates the baseline rotation method based on the antenna - swap idea, and develops the fixed axis rotation maximum - minimum method ? farmm and the equivalent rotation maximum - minimum method ? ermm applicable for static basement and moving vehicle respectively. the former lowers the demands on rotation device while the latter improves the flexibility of antennae installation. meanwhile the dissertation also brings forward an ambiguity function search method which needs only one single epoch data with the outer aided information, and investigates the accuracy requirements for the assistant pointing information
其次，通過與gps等多星系統定向關鍵技術的對比分析，指出雙星定向模糊度確定的難度;在分析現有模糊度求解方法的基礎之上，研究了基於交換天線思想的轉動基線模糊度確定方法，並提出了適合於靜基座的定軸轉動極大/極小值farmm法，以及適合於地面運動載體的等效轉動極大/極小值ermm法，前者降低了對轉動機構的要求，後者則提高了天線安裝的靈活性;同時，提出了一種藉助外部輔助信息的模糊度函數搜索法實現單歷元雙星定向，並分析了對外部輔助單軸姿態信息的精度要求。 -
Yield locus is analyzed when antenna is controlled under either pt mode or at mode. double trapezium velocity locus is designed for pt mode while the helix search algorithm is designed for at mode
對程序跟蹤（ pt ）模式和自動跟蹤（ at ）模式下星間鏈路天線的運動規律進行分析，設計了梯形速度軌跡和螺旋掃描運動軌跡。 -
