地震偏移成像：二维叠后深度偏移（相移法）(Seismic imaging: two-dimensional stack depth migration (phase shift method))

利用扩展卡尔曼算法( EKF)对高动态直接扩频信号的载波相位和频率进行了估计,并利用载波辅助技术测量载波相位的变化值来 校正伪码延时环,减小多普勒频移对伪码延时的影响,得到了精确的延时估计值,提 高了伪码延时锁定环的动态跟踪性能.(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 aid- ing technology. The precise delay estimation is obtained. The dynamic tracking performance of the PN delay loop is improved.)
