The maximum entropy method assumes that the spectrum exists up to the Nyquist frequency. For array processing of low-frequency signals, the spectrum often only exists over part of the wavenumber interval. This paper generalises the maximum entropy methods to correctly model this situation. Simulations are included which show the performance of the technique.
