摘要：
In order to solve the problem of ambiguous tracking and multipath mitigation of new signal time-multiplexed binary offset carrier modulated signal in the global navigation satellite system, this paper proposes an improved strobe correlation method which calculates the correlation of the received TMBOC signal with the W2 strobe waveform in 0.5 code offset and the pseudo-random code code in 0.5 code offset, respectively, and then the two correlations are multiplied. In this way an unambiguous and good symmetrical code discrimination curve is obtained. The characteristics of the obtained code discrimination curve by the proposed method is analyzed and simulated, and the result shows: the proposed method is easy to realize, and the obtained code discrimination curve has good central symmetry, strong multipath mitigation capability and can be used for an unambiguous tracking, so it is more suitable for the TMBOC signal discrimination compared with the existing strobe correlation methods and improved methods. © 2018, The Editorial Board of Journal of Xidian University.
