    • The ocean noise coherence matrix and its rank 

      Harrison, Chris H. (CMRE, 2019/05)
      An expression for the cross-spectral density matrix of ocean noise naturally separates into a Toeplitz part and a Hankel part [Harrison (2017). J. Acoust. Soc. Am. 141, 2812?2820]. The Toeplitz part is shown to be substantially ...

    • Separation of measured noise coherence matrix into Toeplitz and Hankel parts 

      Harrison, Chris H. (CMRE, 2017/08)
      The cross-spectral density of ocean ambient noise is usually estimated from the product of the complex hydrophone signals, each of which already corresponds to the summed responses of sources from all angles. The true ...
