We have determined by computer simulation the optimum correlator arrangement when correcting two-directional phase-aberration with a two-dimensional (2D) array. In the simulation, a 2D phase screen was estimated from the correlation of neighboring signals in the 2D transducer. The difference between a given phase screen and the corresponding estimated phase screen was evaluated to find the optimum correlator arrangement. The optimum arrangement is to locate an equal number of correlators in both the scan and elevation directions with the distance between the neighboring correlators being 0.2 to 0.4 times the phase-screen correlation length.
