Precise Estimation Method of Pseudo\|Random Code Delay of Spread Spectrum System in High Dynamic Environment

LI Xiao min LIU Hui CHENG Lee lung\ ZHANG Qi\|shan (Beijing University of Aeronautics and Astronautics,Dept. of Electronic Engineering)  
The problems met in high dynamic environment during direct spread spectrum system measuring pseudo random (PN) code delay are analyzed, and the effect of Doppler frequency shifted on PN code delay is studied emphatically. Carrier phase and frequency of high dynamic direct spread spectrum signal are estimated through extended Kalman filter (EKF) algorithm. The PN delay loop is adjusted through measuring the varied value of carrier phase with carrier aiding technology. The effect of Doppler shift on PN code delay is reduced through carrier aiding technology. The precise delay estimation is obtained. The dynamic tracking performance of the PN delay loop is improved.
