This article proposes a combined shape estimation system of long linear array based on non-acoustic sensor method and hydrodynamic model solving method. The system makes full use of the non-acoustic sensor information to further solve real-time array shape of the tactical towed array according to the hydrodynamic model. Through the data analysis, this system＇s estimate accuracy can be increased by more than 10% compared with traditional array shape estimation algorithm, which has a higher guiding significance to practical engineering applications.
