ABSTRACT (Continue on reverie eld* It neceeeary and Identity by block number) Investigation is made of a "multiplicative" receiver array to determine its capability as signal detector ard bearing estimator. The same analyses are made of the conventional square-law array for comparison purposes. The probability density functions for the filter outputs of array models are obtained for these arrays for the input signals consisting of monochromatic signals and narrowband additive Gaussian noise. The number of sensor elements, SNR, source bearing, and interelement noise correlation, are treated, as DD (J FORM AN 73 1473 EDITION OF 1 NOV 65 IS OBSOLETE

Time delay estimation for passive sonar signal processing

“…Correlator configurations that both detect and estimate bearing for narrow-band signals are considered by Miller [40] . The problem of processes with random relative phase is treated by Wax [63].…”
