Abstract
A system and method for detecting, tracking and identifying a gas plume. The system comprises a processor and a detector in communication with the processor. The detector is effective to detect spectral radiance from a region of interest to detect first and second detected spectral radiance data with a known time difference. A database is in communication with the processor, the database includes a library. The processor is effective to create at least a first image and a second image from the first and second detected spectral radiance data and co-register the first and second images to produce a first co-registered image and a second co-registered image. The processor is further effective to subtract the first co-registered image from the second co-registered image to produce a difference image and generate a cluster region around a difference region in the difference image. The processor is further effective to analyze the spectral radiance from the cluster region to produce a spectral characteristic curve; and correlate the spectral characteristic curve against the library to identify the gas plume.
