Narrow-Band power detector was applied to indicate the lock status in tracking loops of GPS receiver. Previous researches did not discover the statistical characteristics and mean time to lose lock of detector, thus the threshold selection did not have theoretical support. In this paper, the probability distribution of detector is derived theoretically by stochastic method, and the relationship between the lock probability and carrier to noise (C/N0) of the signal is discovered.
