摘要： Methods and systems are presented for spectral analysis of data generated by one or more sonar sensors. A covariance matrix of the captured sound is derived, denoted by an LxL matrix R, and for each power value which is to be calculated for each direction, a set w of L weights are derived which minimize w H Rw subject to a constraint which is itself a function of a covariance matrix of sound captured by the sensors or based on a theoretical noise model. The set of weights w is used to produce a power spectrum at a particular time instant. Embodiments of the invention can be used to compute two types of spectrum: (i) a spatial spectrum and (ii) a frequency spectrum (or, by extension, a Doppler spectrum). That is, it may be performed in either the spatial or the frequency domain.

The method further includes determining one or more directions relative to a position of one or more of the two or more microphones for the one or more prominent sound sources (1B-1D). The method includes modifying one or more user interface elements displayed on a user interface of a display to provide an indication at least in part of the one or more directions, relative to position of at least one microphone, of the one or more prominent sound sources (1G).
