• The major work is as following : based on the analysis of signal receiving problems when navigation receiver is in high dynamic circumstance , some typical algorithms such as maximum likelihood estimator ( mle ) , extended kalman filter ( ekf ) , frequency lock loop ( fll ) , digital phase lock loop ( pll ) and frequency extended kalman filter ( fekf ) are deduced
  高动态下面临着多普勒频率、多普勒频率变化率较大的问题,给载波跟踪带来了很大困难。本章分析了目前高动态接收机中普遍采用的几种载波跟踪算法,对算法的性能进行了比较。
