Improved data analysis system

Claim 1

A data analysis system comprising: multiple sensors for generating a series of time related data samples from an environment including sets of common wavefronts; means for converting said data samples from analog-to-digital form; means for developing the Fourier transforms relative to the frequency components of the data samples in digital form; means for cross-correlating each frequency component of the Fourier transforms corresponding to each data sample with each like frequency component of the Fourier transform of each other data sample for developing matrices of all such possible correlations for each frequency component; means for integrating the cross-correlation matrices of each frequency component over a determinable time period for producing multiple pluralities of integrated output signals, each plurality representing the signals developed at a particular frequency; means for storing multiple pluralities of synthesized signals, each plurality being representative of incident plane wave power as a function of its angles of arrival at a plurality of sensors and of its frequency; and comparator means for comparing said pluralities of integrated output signals with said pluralities of synthesized signals for producing output signals of relative strength indicative of the direction of the origin of said data samples relative to the directional disposition of said sensors.

Claim 11

A method of analyzing time related data samples developed from an environment including sets of common wavefronts comprising the steps of: converting the data samples from analog to digital form; developing the Fourier transforms relative to the frequency components of the digital data samples; cross-correlating the frequency components of the Fourier transform for developing matrices for all possible correlations for each frequency component; integrating the matrices for each frequency component over a determinable time period; and comparing the integrated matrices with synthesized signals representative of incident plane wave power as a function of its angles of arrival at a sensor array and of its frequency for producing output signals of relative strength indicative of the direction of the origin of the data samples.
