Application review on underwater radiated noise measurement by using a vessel’s own towed array

Compared with the traditional fixed test and auxiliary measurement ship, the measurement of the underwater radiated noise by using a vessel’s own towed array has many advantages, such as flexible, convenient, low cost, and so on. In this paper, the previous researches on this method are summarized. From the view of implementing this technique, the method has been divided into four aspects: towed array design, U-turn manoeuvre, underwater sound propagation and towed array signal processing. Overall, this technology is practical and feasible, and has a good application prospect. Next, combined with a large number of experiments, further study on the selected principle of the towed array and U-turn technical indicators will be done.
