Abstract

Experimental observations of recently predicted correlation-dependent, propagation-induced changes in the spectrum and cross-spectra of a cyclostationary field are reported. An acoustic Young's experiment was conducted in which sources were driven by stationary signals modified by a square wave to make the process cyclostationary. The degree of correlation of the underlying stationary processes were controlled to change the spatial coherence of the sources. The far-zone generalized spectra changed with changing degree of correlation.
