MAXIMUM ENTROPY SIGNAL DETECTION METHOD

摘要

In one aspect of the invention, a method of detecting an elevated signal, including: using a sequence of constant width samples from detector apparatus; summing adjacent populations of adjacent samples from the narrowest to the widest; analyzing each of the populations to determine if the elevated signal is present when compared to background noise; and reporting the elevated signal, hi a further aspect of the invention, there is provided a method of detecting an elevated signal, including: using measurements from each of several different detectors viewing same sample; creating various combinations of different detector measurements; creating a population sample of either all possible detector summations or a subset of physically reasonable summations; analyzing each population sample to determine if the elevated signal is present when compared to background noise; and reporting the elevated signal. In an additional aspect of the invention, there is provided a method of detecting an elevated radiation signal, including: using a measurement of gamma energy from each of several different energy regions from the same radionuclide or radionuclide group within same detector measurement; creating various combinations of different energy regions within that detector measurement; creating a population of either all possible energy region summations or a subset of those physically reasonable summations; analyzing each population to determine if the elevated radiation signal is present when compared to background noise; and reporting the elevated radiation signal.
