To solve the problem of nonhomogeneous clutter suppression for moved target detection in the airborne phased array, this paper presents a new space time adaptive processing (STAP) method which is named D3AR. This method firstly filters the target information of cell under test (CUT) based on the phase information of target. Then constructs the AR model to obtain the clutter characteristic. Finally gets the space orthogonal to the clutter subspace based on the AR filter coefficients. This method doesn't require the adjacent training data and is suited for nonhomogeneous clutter environment. The simulation results demonstrate its effectiveness.
