摘　　要：在考虑多通道非平稳信号干扰及背景噪声的情况下 ,提出了基于自适应参数型时间延时估计方法。该方法能准确地进行多径传输情况下的时间延时估计 ,有效地抑制干扰和噪声的影响。仿真结果说明了该方法的有效性。Taking into account the multi channels disturbance and noises with the non stationary characteristic, time delay estimation based on adaptive parametric approach is proposed. Multi path time delays are estimated precisely with this approach, and disturbances and noises can be refrained effectively. The simulation examples are presented to demonstrate the effectiveness of this novel approach. This time delay method based adaptive parameters approach can be used to location targets in sonar and radar system.
