| Abstract: | The adaptive angle Doppler compensation(A2DC) method can be applied to compensate for the clutter range dependence for non-sidelooking arrays without requiring any navigation data.However,this method suffers from a serious drawback of high computational complexity which limits its real-time application.In this paper,the principle of the A2DC method is first investigated.Then,to address the computational burden,a block processing and projection approximation subspace tracking(PAST) technique is inserted into... |
