%X The rotation rate measurement error produced by back-scatter from a partially coherent source has been investigated. The level of error introduced is shown to be dependent on the phase-modulation frequency. Operation at the correct frequency completely eliminates the coherent backscatter-induced errors. Taking into consideration realistic modulator stability conditions a source with a coherence length of tens of centimetres is feasible in an inertial grade, phase-modulated system.
