基于域值搜索的双频非特殊周跳探测
|
摘要
针对双频周跳探测的多值及如何判断各自频率上周跳问题,提出了一种通过约束双频上周跳的域值,利用无几何距离为主方程的域值搜索周跳探测方法。采用域值搜索算法,不但解决了多值问题,而且能准确探测出各频率上的周跳。通过高采样数据计算验证,该方法不仅能准确探测1s、5s采样率下的周跳,同时对10s、15s采样率数据同样有效。与其它方法相比,该方法准确、可靠,实用性强。
To detect the multi-value of dual-frequency cycle slips and to judge the cycle slips on their own frequencies, this paper proposes a cycle slip detection method of domain search that uses the free-geometry as the dominant equation by constraining the bounds of the dual-frequency cycle slips. Using the domain value search algorithm not only solves the multi-value problem, but also can accurately detect the cycle slip on each frequency. Through the calculation and verification of the high sampling data, this method can not only accurately detect the cycle slip at the sampling rate of 1s and 5s, but also is effective for the 10s and 15s sampling rate data. Compared with other methods, the method is more accurate, reliable and practical.
