Abstract

In the former work, the histogram was effectively used to improve the interference immunity of target velocity estimation based on the cross-spectrum. This paper proposes a new method to eliminate the bias introduced by the histogram and to further improve interference immunity. The equalization window is designed to preserve the cross-spectrum peaks while suppressing the interference peaks. All frequency points are compensated and accumulated to improve the interference immunity. Finally, the simulation and sea trial data verify the effectiveness of the proposed method in this paper.
