| 摘 要： | 从多路径信号对码跟踪精度的影响入手，得出在多路径干扰下，用窄相关器可以部分修正多路径对码环的跟踪误差。微脉冲相关技术与宽的标准相关器和窄相关器在伪距测量精度上相比是一种性能非常好的抗多路径技术。

| Abstract: | From the impact of multipath signal in the precision of code tracking,educed that the tracking error of code loop can be partially corrected by narrow correlator under the multi-path interference. Anew narrow correlator technique-pulse aperture correlator which is based on narrow correlation is introduced. Comparing with wide standard correlator and narrow correlator in the precision of pseudorange measurement, pulse aperture correlator is a very good technique in the performance of anti-multipath. |
