Experimental Study of Radiation Impedance with Effect of Reflected Wave from Sonar Dome

概要

論文の詳細を見る
The radiation impedance of arrayed vibrators is analyzed experimentally when the array has a reflector. To verify the effect of the reflector, the radiation impedance with the reflector was calculated. To estimate the radiation impedance change, the input impedance of the vibrator was calculated using an equivalent circuit model. The input impedance was dependant on the location of the vibrators. The experimental results show a similar tendency to the theoretical results. It is noted that the equivalent circuit model for theoretical analysis is useful for estimating the radiation impedance change caused by the reflected wave.
