Array Shape Distortion and Array Signal Characteristics of A Towed Array under Harsh Sea Conditions
摘要
Abstract
To further improve towed linear array's performance underwater ,the movement of tugs under harsh sea con-ditions is analyzed and the sine random distortion model of towed line array is proposed .ITTC single-parameter standard wave spectrum is applied to modeling ship's linear rolling movments under stochastic waves .Then ,the sine random distor-tion pattern is established based on stress wave theory ,and array signal characteristics are analyzed .Both of these make a basis for beamforming and power spectrum correction of the towed line array with shape distortion .关键词
