| Abstract: | A computer simulation for phase aberration correction is conducted, based on the method of partial array reference,cross-correlation as cost function. It is shown that the best performance can be obtained with 2--8 elements as reference while SNR > 10dB and the aperture includes 128 elements: rms residual phase error is about 0.02 wave length while it is near 0.04 wave length with 1 or 20 elements as reference. Performance of partial array reference is worse than the adjacent element reference when SNR is small. |
