Abstract
An apparatus is provided in which individual transmit elements (18) of a transmit array are actuated in turn in order to interrogate a search volume Signals reflected from the volume are received by one or more reception elements (20) of a receive array and are recorded. The propagation parts to a selected cell are calculated and appropriate phase and or time shifts are inserted into the recorded data to simulate, post reception, the shifts that would have occurred if either or both of the transmit and receive arrays had been focused on the cell using phased array beam steering techniques.
