Abstract:Strong direct path interference suppression is one of the problems to be solved in AUVs' cluster system which has the advantages of concealment, precision, anti-jamming capability and function distance. In order to estimate the target direction,3 methods of beamforming,including covariance matrix taper(CMT) condition,null-constrained condition and second-order cone programing(SOCP) constraint condition, are used to restrain direct path interference suppression separately in this paper. Comparing the 3 methods … Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
