Then the phase trajectory is estimated based on mmse criterion, and the frequency offset and initial phase can be achieved
在此基礎上，基於mmse準則計算載波相位的軌跡，得到頻差和初始相位。 -
The missile ’ s lunch point parameters and burnout point parameters are estimated using boost phase state estimation, and the impact point is predicted according to ellipse trajectory theory. and the effect of the estimation error of the burnout point on the impact estimate precision is analyzed
應用主動段的狀態估計值估計了導彈發射點參數和關機點參數，根據橢圓彈道理論進行了落點預報，並分析了關機點參數估計誤差對落點估計精度的影響。 -
Secondly, aiming at measurement being only from one satellite and the ekf being not stable, the measure equation is improved. transforming the form of angle measurements by the imaging theory, linearization of measure equation is realized by fake data of measurement. parameter of ballistic missile trajectory is estimated by using ekf, and the simulation shows that the unstabilization problem of ekf with true measurements is solved by using ekf with fake measurements
在僅有一顆預警衛星能夠觀測到目標的情況下，針對擴展卡爾曼濾波不穩定的問題，對觀測方程進行改進，利用光學成像系統的原理，將測量量進行變換，並利用新生成的偽測量量使測量方程線性化，再利用擴展卡爾曼濾波演算法對目標的彈道參數進行估計，最後，通過數學模擬來證明利用偽測量量的擴展卡爾曼濾波解決了單顆衛星觀測時利用真實測量量的擴展卡爾曼濾波不穩定的問題。 -
The unknown parameters are estimated in the time domain. the global uniformly exactly tracking of the trajectory on the specified time interval is achieved and the boundedness of all signals of the closed - loop system is ensured
在時域中估計系統的未知參數，所提出的自適應迭代學習控制器在給定的區間上實現了對目標軌線的全局一致精確跟蹤，同時保證了閉環系統所有信號全局一致有界。
