摘要:
针对Warping变换在非理想波导中的变换效果受海洋环境影响的问题,在传统的Warping变换的基础上,对非理想波导下的Warping变换公式进行修正,使修正后的Warping变换更适用于非理想波导下宽带脉冲声压信号的简正波分离和提取。本文给出了基于海底相移参数P的适用于具有均匀半无限海底的非理想波导的Warping变换修正公式。修正因子只与海底相移参数、海深、海水中平均声速等海洋环境参数有关,与其他海底参数无关,减少了Warping变换的修正难度。与已有的Warping变换修正公式相比,本文提出的对Warping变换的修正方法,所需的环境参数少,在实际应用中计算简单、应用方便,更具有实际应用意义。数值仿真和海上实验数据处理结果证明了该方法的有效性。
