Combination algorithm fully use the advantage of the ukf for small noise and the upf ’ s non - sensitivity to noise, when noise increase, upf can also estimate the missile ’ s states well
聯合演算法充分利用了ukf在噪聲較小時估計效果較好和upf對噪聲不敏感的特性，使得當觀測噪聲突然增大后，利用upf演算法仍能使導彈位置和速度誤差收斂，達到有效預警的目的。 -
The united people ' s front ( upf ), which had been the third - largest nepalese political party in 1991, suffered from a series of splits during the 1990s rivaled only by cpn
聯合人民陣線（ upf ） ，在1991年曾是尼泊爾第三大政黨，在20世紀90年代經歷了一系列的僅次於尼共的分裂。 -
Aiming at this problem, particle filter is studied. combination filter algorithm is constituted using ukf and improved particle filter ( upf ), and missile ’ s states with noise increase are estimated
針對這個問題，研究了粒子濾波演算法，利用ukf和改進的粒子濾波（ upf ）組成聯合濾波估計演算法，可以有效估計具有噪聲增大時導彈主動段運動狀態。 -
The nonlinear problem is inevitable in bearing - only target tracking problem. here the monte carlo based nonlinear filters are compared with the classical extended kalman filter ( ekf ) in this field : the unscented kalman filter ( ukf ), the particle filter ( pf ) and the unscented particle filter ( upf ). furthermore, a multi - sensor passive tracking algorithm, through combining the ukf and probability data association ( pda ), is provided for bearing - only target tracking in dense clutters
本文將典型的montecarlo非線性濾波器? unscentedkalmanfilter （ ukf ） 、 particlefilter （ pf ）和unscentedparticlefilter （ upf ）應用於被動定位跟蹤，並在二維空間目標跟蹤模擬中與經典的擴展卡爾曼濾波演算法（ ekf ）進行了對比；本文將ukf演算法與概率數據關聯演算法（ pda ）相結合，給出了適用於雜波環境下多站被動式跟蹤的ukfpda演算法。
