  1. 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度的一個近似常量,應用擴展卡爾曼濾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、準確地估計推進發動機的質量秒耗量和向機動目標施的實際推力
  2. The direct digital frequency synthesizer is a kind of fully digitized frequency synthesizer, which consists of the phase accumulator, the sine look - up table, the digital to analog converter and the low band filter. it is of high frequency resolution, fast frequency switching speed, low phase noise, the ability to switch frequencies while maintaining constant phase, and the ability to producing arbitrary waveforms
