With coupler embedded and acceleration sensitivity compensation design, the structure symmetry is insured, which can induce the acceleration sensitivity effectively. The acceleration sensitivity compensation design also improves the production efficiency of FOH for towed linear array application.2. A good theoretical simulation platform, utilizing the method of elastic mechanics and the finite element method, is established, which can provide an effect predictive design for FOH. The experimental results are in good agreement with the theoretical analysises.3. Some key technology problems in the making of FOH for towed linear array application are conquered. The new developed FOH, with an acoustic sensitivity of -143.0dB, has acceleration sensitivity less than -30dB, which exceeded to results from other international reports.
