A spacetime two dimensional high resolution estimation method that is applied to achieve dopplershift frequency and directionofarrival(DOA) isolateddimensional estimation is introduced . In this method the authors use a timedomain ESPRIT algorithm to achieve blind dopplershift estimation and a projectiontransform method in timedomain to estimate the directionofarrival(DOA).The result of computer simulation illustrats that the new method is robust and highresolutional,which can not only distinguish signals at all directions, but also separate anear signals.
