Patent ID: 7916947

Claim:
A method for analyzing hyperspectral data, the method comprising: collecting a first plurality of hyperspectral data sets of a scene using a hyperspectral imager during a period where no gas is expected to be present in the scene; analyzing the first plurality of hyperspectral data sets using at least one gas plume detection logic, wherein the at least one gas plume detection logic is executed using detection threshold, wherein the at least one gas plume detection logic detects each occurrence of an observed hyperspectral signature; generating a histogram for all occurrences of each observed hyperspectral signature which is detected using the at least one gas plume detection logic; determining a probability of false alarm (PFA) for all occurrences of each observed hyperspectral signature based on the histogram; collecting a second plurality of hyperspectral data sets of the scene using the hyperspectral imager; and analyzing the second plurality of hyperspectral data sets using the at least one gas plume detection logic and the probability of false alarm (PFA) to determine if any gas is present in the scene.
