  • In this paper, the method to determine the bearings and ranges to three highlight sections of a ship is proposed and studied by means of a small rhombic acoustic intensity array. The simulation results show that the method is correct. An experimental facility is designed and manufactured. The scaledown experiment determining the bearings and ranges to three highlight sections of a ship is completed in serni-anechoic room. The experimental results are consistent with simulation results.
