On the basis of the Cramer-rao bound(CRB) covariance matrix formula of direction-of-arrival(DOA) estimation under the given condition derived by Stoica P and Nethorai Arye.There exists some problems on the parameter setting for this CRB algorithm.Aim at the problem,this paper made a further modification on the algorithm and simplified the preferences which effectively solved the problem of traditional CRB parameter selection and were convenient for performance analysis of experimental results,which were more close to engineering application.The results of computer simulation have shows that the modified CRB agrees well with the theoretical results.Consequently it will have a better applying foreground.
