Abstract

Current passive reverberation methods have certain limitations when applied into practice, which would null boundary reverberation and target echo simultaneously. As a solution, a passive reverberation nulling method based on reverberation subspace estimation for target enhancement is proposed in this paper. In this method, the reverberation subspace for target range cell is not obtained directly by the return signals scattered from the target range cell but from the range cells located neighboring the target range cell. So that the reverberation components embodied in target echo is suppressed by passive reverberation nulling. Experimental results demonstrate the efficacy performance of the proposed method for echo-to-reverberation enhancement.
