摘　　要：从多个具有相同已知波形且在到达时间上相隔很近的叠加回波信号中估计各个回波信号的幅度和到达时间，是一个比较困难的超分辨率时延估计问题。首先对这一问题的研究现状进行了综述，然后，介绍了笔者在此方面取得的最新研究进展，包括一类适用于不同应用背景的简单有效算法。所提出的新方法在许多领域中具有广泛的应用前景。Time delay estimation is a well-known problem that occurs in many fields. When multiple echoes are closely spaced in arrival time, super resolution time delay estimation is required, which is a notorious difficult problem. In this paper, the authors first summarized the recent status of the research on super resolution time delay estimation techniques. Then some recent progresses of our research on this topic are introduced, including a novel family of computationally efficient algorithms with different applications. The proposed algorithms have a wide variety of application areas.
