Abstract
A calibration system for an infrared imaging system includes an infrared sensor having a sensor model for imaging a target having a target spectral signature. The infrared imaging system includes an atmospheric model having atmospheric spectral values. The calibration system comprises a blackbody calibration source having a calibration source spectral signature and a computer for receiving the sensor model, the target spectral signature, the calibration source spectral signature and the atmospheric spectral values. The computer predicts a target spectral signature propagation at the infrared sensor and matches the target spectral signature propagation with the calibration source spectral signature propagation to determine a blackbody calibration source temperature for radiometric calibration of the infrared sensor.
