Abstract

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 the A²DC method and a fast A²DC (FA²DC) method is proposed. Simulation results are presented to show that these two compensation methods demonstrate approximately the same performance, but the proposed method reduces the computational complexity significantly.

Key words: non-sidelooking array, adaptive angle Doppler compensation, projection approximation subspace tracking, block processing, space time adaptive processing
