Abstract:
1. A method for estimating a target specific spectral distribution on at least one target over a period of at least one time measurement in a sensor space having at least one spatial cell and at least one spectral cell comprising: providing a spectral probability density function; calculating the component spatial cell probabilities for each said time measurement, for each said target and for the total number of said spatial cells; calculating the combined component spatial and spectral cell probabilities by taking the matrix outer product of said component spatial cell probabilities and said provided spectral probability density function for each said target; summing said combined component spatial and spectral cell probabilities for all said targets to obtain a total combined spatial and spectral cell probability for all said targets; summing said total combined spatial and spectral cell probabilities for all said targets over all spectral cells and all spatial cells to obtain a total sensor space probability; calculating an expected sensor space measurement for all spectral cells and all spatial cells; determining the relative mode contributions for all said targets using the combined component spatial and spectral cell probabilities and the total combined spatial and spectral cell probability for all said targets; calculating the average spectral power on each said target using the relative mode contributions for all targets, the expected sensor space measurement for all spectral cells and spatial cells, the combined component spatial and spectral cell probabilities and the total combined spatial and spectral cell probability for all said targets over all time measurements; linking all of the average spectral powers of all of the targets to obtain a spectral distribution estimate for each of the targets; and displaying said spectral distribution estimates on a computer display screen for each said target.
