The potential ability of the Applebaum type adaptive array to suppress the multipath signals is examined. The output Signal-to-Noise Ratio is expressed in terms of (1) the input SNR. (2) relative multipath signal amplitude, and (3) ambient noise when a multipath component is present Computer simulation is done on several performance measures to learn that the performance of the array depends upon the magnitude and the phase of the correlation coefficient. It is also shown that the performance is maximized when the phase of the correlation coefficient is zero degree.
