Abstract:
A system for adjusting phase centers of a receiving array in real time. In one embodiment, a transmitter transmits a sequence of pings. Receiving elements are grouped into staves and summed prior to subsequent processing, and the groups are selected so that the phase center on a ping is substantially in the same location as another phase center on a previous ping.
