Method of Converting Received Data to a Two-Dimensional Color Map

Abstract

Beams of sampled data are converted into a two-dimensional color map thereof. Fourier transforms are performed on range cells of each beam with each transform being sampled M times where M is defined by M discrete sets of red, green and blue intensity values of a color spectrum. For each range cell in each beam, each sample of the corresponding M-sampled Fourier transform is multiplied by a corresponding one of the red, green and blue intensity values from a corresponding one of the M discrete sets thereof. Each of the resulting M red values, M green values and M blue values are averaged. As a result, a triplet is defined for each range cell by the averaged values. For each triplet, the minimum thereof is used to reduce the triplet's averaged values to thereby form a corresponding re-valued triplet. The resulting array of re-valued triplets are normalized across all of the range cells with the resulting array of re-valued triplets so-normalized being used to generate a two-dimensional color display.
