The effect of the characteristics of a generic distributed fiber sensor based on stimulated Brillouin scattering on the amplitude of the response is analyzed and a relation between the measurement noise on the time traces and the error on the determination of the Brillouin frequency shift is established. This makes possible to propose a simple figure-of-merit to fairly compare the performance of Brillouin distributed sensing systems.
