The large field of view (FOV) imaging radiometers performed as remote sensors are extensively used in remote sensing and surveillance applications. The pre-launch test and radiance calibration of large FOV imaging remote sensors have resulted in the development of calibration techniques. One of these calibration techniques is the employment of large-area integrating sphere radiation sources as radiance transfer standards. To meet the calibration requirements of large FOV imaging remote sensors, a large-area integrating sphere uniform radiation source (ISURS) based on a 1600 mm diameter internally illuminated integrating sphere with a 620 mm diameter exit port is designed and manufactured. This large-area integrating sphere radiation source has been used for pre-launch calibration of large FOV imaging remote sensors which fly aboard Erath-observing satellites.
