On the resolution capacity of wideband sensor arrays: Further results

Abstract

The fundamental limits on the maximum number Dmax of cochannel wideband emitters uniquely resolvable by a passive K-element sensor array are studied. It is shown that for uncorrelated emitters Dmax is only O(K√L), where L is the measurement time-bandwidth product. These results extend the authors' recent result, that for a uniform linear array with uncorrelated cochannel wideband emitters Dmax ≈ K L/2. Hence, Dmax of a given array for cochannel wideband signals is essentially limited only by the observation interval, rather than by the number of sensors.
