【摘要】 本文对实验数据进行了有限长加肋和无肋圆柱壳在时域和频域上的回声信号特性的分析,比较了不同入射信号类型(CW 脉冲和 LMF 调频脉冲)、不同脉冲宽度以及壳内是否充水的条件下,二者的差别。理论和实验研究均得到一些有意义的结论。更多还原

【Abstract】 In this paper,datum were processed and the echo characteristics were analyzedfor limited ribbed cylindrical shell and another without ribs in the domains of time and frequency,the difference were compared in the case of two type of incident signal (CW pulseand Linear Frequency Modulation pulse), different pulse width and cylindrical shell with and without water.The studies on both theory and experiment drew some significative conclusion.更多还原
