CAPABILITIES OF MULTIPLICATIVE ARRAY PROCESSORS AS SIGNAL DETECTOR AND BEARING ESTIMATOR

摘要

Investigation is made of a 'multiplicative' receiver array to determine its capability as signal detector and 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 parameters of the distribution, and their influences are displayed graphically. Based on these probability density functions for the square-law and multiplicative array processors, the authors then examine their performances as signal detectors and bearing estimators.
