摘要
超声波声场中存在主声束和副瓣声束,在特定情况下第一副瓣声束会引起超声波检测结果的误判。通过对第一副瓣声束相关参数的计算,得出横波斜探头第一副瓣声束的位置,并作了相应的试验验证。提出了对副瓣引起的干扰回波的鉴别方法。
The first minor lobe beam could result in some wrong judgment under unusual condition.Through calculating the corresponding parameters of the first minor lobe beam,its location was obtained and further verified by related experiment.The differentiation method of the disturbing echo caused by minor lobe beam was proposed.
