Journal of the Acoustical Society of America, 71(1), 97-99. doi: 10.1121/1.3872480001-4966http://hdl.handle.net/10919/52602This paper presents approximations for the rms error of the maximum likelihood estimator of the direction of a plane wave incident on a random array. The sensor locations are assumed to be realizations of independent, identically distributed random vectors. The second part of the paper presents an asymptotically unbiased estimator of the noise wavenumber spectrum from random array data.3 pagesapplication/pdfen-USIn CopyrightNoise propagationRandom noiseEstimating signal and noise using a random arrayArticle - Refereedhttp://scitation.aip.org/content/asa/journal/jasa/71/1/10.1121/1.387248Journal of the Acoustical Society of Americahttps://doi.org/10.1121/1.387248
