偽線性主動段彈道估計(jì)方法
The Trajectory Estimation in Boost-Phase Using Pseudolinear Estimator
-
摘要: 該文主要分析了星載被動傳感器對目標(biāo)的運(yùn)動參數(shù)估計(jì)問題,它也是空間預(yù)警系統(tǒng)的關(guān)鍵技術(shù)之一.文中提出的偽線性測量-卡爾曼濾波(PM-KF)的彈道估計(jì)方法減小了測量方程非線性所帶來的估計(jì)誤差,較之EKF濾波有更好的估計(jì)精度.

Abstract: Trajectory estimation using the measurement of arrival angles from space-based infrared sensors is one of the key technologies in the space early warning system. This paper presents a pseudolinear measure-Kalman estimator for trajectory estimation in boost-phase. Compared with EKF and CRLB, this estimator is more precise. -
