Abstract
An analytical expression for the variance of MUSIC source location estimates is derived under the assumption that the detection step has already taken place, resulting in an underestimation of the source number. The analytic predictions are compared with Monte-Carlo simulation results for beam-space MUSIC. The derived variance expression is more general than those reported to date and is also valid for other situations where the asymptotic correlation matrix yields biased source estimates
