外文摘要：This paper deals with the 3-D moving source localization using time difference of arrival(TDOA),frequency difference of arrival(FDOA),angle of arrival(AOA)and AOA rate measurements,gathered from a set of spatially distributed receivers.The TDOA,FDOA,AOA and AOA rate measurement equations were firstly established according to the space geometric rela-tionship of the source relative to the receivers.Then an efficient closed-form algorithm for source position and ve-locity estimation from the quadruple hybrid measure-ments was proposed.The proposed algorithm converts the nonlinear measurement equations into a linear set of equations,which can then be used to estimate the source position and velocity applying weighted least square(WLS)minimization.In contrast to existing two-stage WLS algorithms,the proposed algorithm does not intro-duce any nuisance parameters and requires merely one-stage,which enables for source localization with the few-est receivers necessary.Theoretical accuracy analysis shows that the proposed algorithm reaches the Cramer-Rao lower bound,and simulation studies corroborate the efficiency and superiority of the proposed algorithm over other algorithms.
