摘要：

Using the Cramer-Rao bound (CRB) as an indicator of potential performance, in this work we study a moving array's ability to estimate parameters of a narrow-band signal. Specifically, the hybrid CRB on source frequency and bearing are studied for signals containing both random fading parameters and unknown deterministic ones. The derived hybrid CRB is compared to the traditional deterministic CRB [1] and the Gaussian CRB [2] in the literature. The study provides information for the effective utilization of a moving aperture in estimating source bearing and frequency.
