摘要：

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.
