摘    要:拖曳线列阵声纳以低频、大孔径等特点而受到关注。作为湿端的主要组成部分,拖线阵的发展也比较迅速。由于应用较早,液态拖线阵技术已经比较成熟。相比于液态拖线阵,固态拖线阵具有自身的特点,因此近年来对固态拖线阵的研究也逐渐增多。为了比较两种成阵工艺对拖曳线列阵性能的影响,进行了湖试,通过对湖试数据进行分析,比较两种拖线阵中阵元一致性和拖线阵波束形成性能的差异。结果表明,在阵元一致性方面,液态拖线阵和固态拖线阵的性能基本相似;在波束形成性能方面,静态时两者性能无明显的差别;在拖曳状态下,固态拖线阵对拖曳时产生的噪声敏感性低,因而具有更好的波束形成性能。

关 键 词:固态拖线阵  液态拖线阵  阵元一致性  波束形成性能

Abstract:Towed linear array sonar attracts attention for its properties of low frequency and large aperture.As an important part of the wet-end,the towed linear array has been developed rapidly.The liquid towed linear array is mature due to being used earlier.Meanwhile,more studies on solid towed linear array have been done for its special feature.To compare the consistency of hydrophones and the beam forming performance between the two kinds of towed linear arrays,the lake experimental results are presented.The analysis results show that the liquid towed linear array has almost the same performance as the solid towed linear array in consistency among different hydrophones.In the aspect of beam forming,the performances of the two kinds of arrays have no significant differences in static state;but under the condition of towing,the solid towed linear array is better than the liquid towed linear array because it’s less sensitive to the noise while towing.
Keywords:solid towed linear array  liquid towed linear array  consistency of hydrophones  beam forming performance
