The authors study the effects of sensor pattern and sensor position perturbations on the angle estimation performance bound for multiple narrow-band sources. The Cramer-Rao lower bound (CRLB) is used with a probabilistic modeling of the perturbations. The CRLBs of a linear uniform array under sensor position and pattern perturbations are evaluated in detail for the case of two narrowband sources.
