Abstract
We aim to find an unbiased estimate of the spectral content of an acoustic source in a shallow water channel, from measurements on an array of acoustic sensors. The acoustic source spectrum is assumed to be a mixture of discrete and continuous spectral components. Due to multipath arrival at the sensors the spectral distribution at any individual sensor is no longer simply a scaled version of the source spectrum. Consequently, spectra associated with individual sensor signals produce biased estimates of the source spectrum.
