摘要

提出了一种改进非平稳信号的到达方向估计的方法。这是一种情况，例如在主动声纳系统中，当一个已知的波形被传输时，反射是由一组水听器测量的。结果表明，对于一类信号，在方位角估计中可以利用信号的相关知识来提高分辨率

Toeplitz-Hankel decomposition for direction of arrival estimation using transient signals

A method is described which can improve the direction-of-arrival estimation when the signal is nonstationary but of a known form. This is the case, e.g. in an active sonar system, when a known waveform is transmitted and the reflections are measured by an array of hydrophones. It is shown that for a class of signals, the knowledge about the signal can be used to improve the resolution in azimuth estimation.<>
