Abstract
Capon has described an estimator that can be used to discriminate between wavefronts incident upon an array of sensors from different directions. It is shown here that for a received field consisting of a single "signal" wavefront and an uncorrelated "noise" component, Capon\´s estimator displays less angular resolution than the conventional estimator when the amplitudes and the delays of the received wavefront are not known within a given tolerance.
