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.
