High‐sensitive acquisition of signals for inter‐satellite links of navigation constellation. Issue 23 (1st November 2015) - Tang, Yinyin
Abstract : The method changing non‐coherent integration to coherent integration is proposed to increase the sensitivity of signal acquisition. A phase jump occurs between the consecutive blocks when the carrier frequency is circularly shifted and this leads to the problem of direct accumulation. A compensation factor is exploited to solve the problem. Monte Carlo simulation results show that the method can improve the sensitivity of acquiring weak signals.
