摘要
文章采用KZK方程数值求解均匀平面阵、聚焦阵及非衍射阵形成的参量阵波束近场声场 ,比较了不同波束声轴上的原、差频声压级及声截面。
The nearfields of parametric array produced by circular focus beam,circular uniform beam and nondiffracting beam was calculated by using KZK equation.The numeric result of the sound levels with difference frequency on the sound axises and the beam patterns were analyzed.
