在近年來提出的基於質點運動學原理的單站無源定位理論基礎上，本文第二章提出了幾種在角度測量的基礎上增加角度變化率及相對運動的離心加速度等運動學參數的單站無源測量模型，並對它們進行了分析和模擬；第三章分別對利用角度及其變化率信息定位和利用離心加速度信息定位的可觀測性進行分析並得到了相應的可觀測條件；第四章針對傳統擴展卡爾曼（ ekf ）方法的缺點，提出了一種修正協方差的擴展卡爾曼濾波（ mvefk ）方法，並將其和ekf 、 mgekf 、 iekf等常用的單站無源定位濾波方法進行了性能模擬比較；第五章通過引入雷達機動目標跟蹤方法和模型，提出了利用角度及其變化率對機動輻射源跟蹤的多級噪聲自適應方法和imm方法；第六章主要對角度變化率和離心加速度參數的獲取技術進行了研究，提出了幾種高精度測量脈沖序列多普勒頻率變化率的方法。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Then, we use a simulation method to create a large number of radar measurement values, produce a quantity of random numbers using computer software and add them to the radar measurement values, we use kallman filtering method to calculate the location, velocity and trajectory coefficient of the target at the moment of the final tracking point, and use the numerical solving method of differential equation to calculate the trajectory, the location of the hostile artillery or the impact point of its own projectiles, finally, we calculate statistically the random error of the tracking system and analyze the location accuracy
然後採用模擬模擬方法獲得大量的雷達測量值，由計算機軟體產生大量的隨機數，加入雷達測量值中，用卡爾曼濾波法計算出最後跟蹤點時刻的目標位置、速度和彈道系數，再用微分方程數值解法計算出整個彈道軌跡、計算出敵方炮位的位置或己方炮彈的落點，最後統計出跟蹤系統的隨機誤差，分析定位精度。But spectacular batting displays by the likes of mark mcgwire and sammy sosa, along with top quality pitching from roger clemens, randy johnson, pedro martinez, and greg maddux have kept the spectators coming and the cash flowing through america ' s favorite sport
