Performance Analysis of Solid Towed Array

Towed line array sonar has attracted attention for its property of low frequency and big aperture. As an important part of the wet-end, the towed array has developed rapidly. The liquid towed array is more mature for its being used earlier. Meanwhile, more studies on solid towed array have been taken for its special feature. To analyze the performances on the phase consistency of hydrophones and the beam forming performance of the solid towed array, the lake trail results are presented. The analysis results show that the solid towed array has good performance on phase consistency among different hydrophones and on beam forming. Especially under the condition of being towed, the solid towed array has better performance for it is less sensitive to the vibration noise.
