主　　题：radial velocity estimation ambiguity wideband radar system 

摘      要：Radial velocity estimation used in wide-band radar systems is *** analyzing the signal of cross-correlation output of adjacent echoes,it is found that the frequency and phase of the cross-correlation output are related to the target’s radial *** the precision of the phase estimation is higher than that of the frequency,a phase-based velocity estimator is ***,the ambiguity problem exists in the phase estimators,and thus the estimation of the cross-correlation of adjacent echoes(CCAE)is used to calculate the ambiguity *** root-mean-square-error(RMSE)of the proposed estimator is *** results show that the performance of the proposed method is better than that of the frequency-based estimator.
