Abstract:
1. A method of converting sensor array data into a two-dimensional color map thereof, comprising the steps of: providing adjacent beams of sensor array data; dividing each of said beams into a plurality of cells with each of said cells having N samples of said sensor array data associated therewith; generating a power spectral density (PSD) curve for each of said cells in each of said beams using said N samples associated therewith; providing a color spectrum defined by M discrete sets of red, green and blue intensity values; generating M samples of said PSD curve for each of said cells in each of said beams; multiplying, for each of said cells in each of said beams, each of said M samples of said PSD curve by a corresponding one of said red, green and blue intensity values from a corresponding one of said M discrete sets to generate, for each of said cells in each of said beams, M red values, M green values and M blue values; averaging, for each of said cells in each of said beams, (i) said M red values to generate an averaged red value, (ii) said M green values to generate an averaged green value, and (iii) said M blue values to generate an averaged blue value, wherein a triplet is defined for each of said cells by said averaged red value, said averaged green value and said averaged blue value; selecting, for each said triplet, a minimum from said averaged red value, said averaged green value and said averaged blue value associated therewith; reducing, for each said triplet, said averaged red value, said averaged green value and said averaged blue value associated therewith, by the value of said minimum wherein a corresponding re-valued triplet is formed and is defined by a revalued red value, a revalued green value and a revalued blue value; normalizing, across all of said cells, said revalued red value, said revalued green value and said revalued blue value associated with each said re-valued triplet; and generating a two-dimensional display using each said re-valued triplet so-normalized.
