Previous phased array research using anti-phase sources has shown that the phase response to an object scanned through a heavily scattering medium provides information about object position but none about size. In this paper it is demonstrated that controlling the relative phase between the sources enables different phase gradients to be set within the medium. The consequence of this is that the phase response is dependent on the size of an object whilst still maintaining localization information. Furthermore, it is demonstrated that the phase response can be tuned to be most sensitive to the object size under investigation.
先前使用反相源的相控阵研究表明，通过强散射介质扫描物体时的相位响应能提供有关物体位置的信息，但无法提供有关物体大小的信息。本文证明，控制源之间的相对相位可在介质内设置不同的相位梯度。这样做的结果是，相位响应取决于物体的大小，同时仍能保持定位信息。此外，还证明了可以将相位响应调整为对所研究的物体大小最为敏感。
