ABSTRACT
This paper analyses the performance of the maximum likelihood closed loop circuits proposed in [4] for phase aberration correction in phased array imaging systems. This analysis is helpful in designing and also in determining the tracking mode phase error variance performance of both closed loop circuits (1-D and 2-D). It is an approximate analysis, suitable under small errors conditions, and considered accurate for high values of the signal to noise ratio.1997 IEEE Transactions on Ultrasonics, Ferroelectrics, and Frequency Control 44:271-286
