摘　　要：排除邻弹干扰是深水炸弹主动探测技术中的一个重要问题。针对此问题,经过理论研究,提出一种基于多普勒频移原理和AR模型功率谱估计的信号特征提取方法,并进行仿真分析,证明了这种方法可以有效区分目标信号和邻弹信号,从而有效排除邻弹干扰。Eliminating the jamming from neighborhood bomb is important in active detection technology of depth bomb. Aiming at the problem,this paper puts forwards a extraction method of signal feature based on Doppler shift theory and AR model power spectrum estimation,and simulates and analyzes it, proves that the method can distinguish between the target signal and the neighborhood bomb signal in order to eliminate the jamming from the neighborhood bomb effectively.

关 键 词：多普勒频移 特征提取 AR模型 功率谱
