This work derives the Cramer-Rao lower bound CRLB for an acoustic target and sensor localization system in which the noise characteristics depend on the location of the source. The system itself has been previously examined, but without deriving the CRLB and showing the statistical efficiency of the estimator used. Two different versions of the CRLB are derived, one in which direction of arrival DOA and range measurements are available full-position CRLB , and one in which only DOA measurements are available bearing-only CRLB . In both cases, the estimator is found to be statistically efficient but, depending on the sensor-target geometry, the range measurements may or may not significantly contribute to the accuracy of target localization.
