An on - line minimum - variance estimator was developed for thrust acceleration applied to orbit transfer using discrete - time radar measurements. the mass - flow - rate of propellant was selected as a state variant, which was estimated by employing an integral state model and ekf filter. the variation equations for measurement vector to mass - flow - rate have been established to linearize the discrete - time measurement equations. the algorithm has applied successfully to maneuver process in commanding satellite into geo - stationary orbit. the results show that the algorithm developed here can monitor and determine whether engine works well or failure precisely and quickly during orbit transfer process
飛行器軌道機動過程中，為跟蹤、定位機動目標和干預機動控制過程，需要統計處理離散的雷達觀測量實時估計推進發動機的推力，進而確定飛行器的瞬時軌道參數.本文所述演算法是該工程問題的探討和解決方案.文章建立了軌道機動過程中連續變質量運動模型和離散雷達量測模型，推進發動機的質量秒耗量作為表徵推力加速度的一個近似常量，應用擴展卡爾曼濾波對離散的雷達測量數據進行順序統計處理給出秒耗量的最小方差估計;文章詳細地推導了線性化量測模型的變分方程和觀測矩陣;模擬結果表明該演算法能快速、準確地估計推進發動機的質量秒耗量和向機動目標施加的實際推力 -
At present, many fields remain to further research, especially the profound combination of gis technique with ece ( estuarine and coastal engineering ), which should be developed for the purposes as follows : ( 1 ) to serve the huge comprehensive work in changeable natural conditions and difficult construction conditions which takes a long period and covers a large region, e. g. the regulation work of deepwater channel in the yre ( yangtze river estuary ) ( 2 ) to combine the gis with applied numerical model ( 3 ) to study the hydrodynamic processes and characteristics of waves, tidal currents and sediment transport, as well as the affection carried by the regulation work in an estuary ( 4 ) to monitor and to analyze ees ( evolution of erosion and sedimentation ) and the variation of riverbed ( 5 ) to play a role of dynamic supervising of a engineering project
目前尚有許多有待進一步研究的領域，尤其是以服務于長江口深水航道治理這樣規模大、周期長、影響區域廣、自然條件復雜、施工情況多變的國家重點工程為目的，將gis與專業應用數學模型結合，對河口海岸波浪、潮流、泥沙運動的動力機制，以及整治工程建築物對其影響的研究，對入海航道沖淤和河勢演變的監測分析，對施工進展和工程效果實現「動態」監控和管理，尚缺乏同gis技術的深入有效結合。 -
