文章首先分析了延迟锁定环在突发模式下码相位测量精度低的问题,然后建立了用于扩频信号伪码相位估计的卡尔曼滤波模型,并分析了该卡尔曼滤波器最优运行和提高测量精度的条件,提出用宽带延迟锁定环引导卡尔曼滤波的方法对突发扩频信号的码相位进行精确估计。通过仿真对比了在突发扩频信号下该方法与单独使用延迟锁定环的性能情况。 Firstly, the problem of low accuracy of code phase measurement of delay locked loop in burst mode is analyzed. Then, a Kalman filter model for phase estimation of the pseudo-code of spread spectrum signal is established, and the optimal operation of the Kalman filter and Improve the measurement accuracy of the conditions, proposed a wideband delay locked loop guided Kalman filter method for the burst spread-spectrum signal phase of the code to accurately estimate. The performance of this method and the delay locked loop alone are compared under the condition of burst spread spectrum signal by simulation.
