摘　　要：作为研制各类导航系统接收机设备的一项关键技术,窄相关技术的优化设计可以有效抑制由热噪声带来的跟踪误差,最终提高伪码的测量精度。在介绍了窄相关技术的基本原理和实现方法的基础上,研究了窄相关技术提高伪码跟踪精度的理论,并通过Matlab仿真平台对窄相关技术进行了仿真分析。The narrow correlator technology is the key technology in the research ot the navigation receiver. Optimal design can reduce the tracking errors in the presence of noise. The basic principle and the implementation method of the narrow spacing was discussed in this paper. The theory that improved code tracking accuracy with the narrow eorrelator technology is studied, and the emulation for the narrow correlator technology in the navigation receivers is also done by Matlab simulation platform.
