The position and orientation of each element’s phase center and the relative delay must be known in order to perform multi-element signal processing. Hence, it is convenient to include these parameters directly as metadata.

A coordinate is associated with a cluster. The origin and orientation of this frame is specified with respect to the platform coordinate frame.
