提出用脉宽２．２ｍｓ、周期４０ｍｓ的等周期脉冲序列测浅海声信道“时域衰落”现象的方法。只要记录到足够长的样本是随机平稳的，而且样本的记录时间比信道的相关时间Ｔ＿ｃ短，数据经微机处理，对信道“时域衰落”的实测结果和理论相符合，重复性也好，说明了这种方法是可行的。 A method of measuring the “time-domain fading” of shallow-sea acoustic channels by using pulse sequences of 2.2ms pulse duration and 40ms period is proposed. As long as the sample recorded long enough is stochastic and stable, and the sample recording time is shorter than the channel related time T_c, the data is processed by the microcomputer, the measured results of the channel “time-domain fading” are consistent with the theory and the repeatability is good, It shows that this method is feasible.
