摘要：

The AHI (Airborne Hyperspectral Imager) system was designed to detect the presence of buried land mines from the air through detection of a long wave IR observable associated with mine installation. The system is a helicopter-borne LWIR hyperspectral imager with real time on-board radiometric calibration and mine detection. It collects hyperspectral imagery from 7.5 to 11.5 mu m in either 256 or 32 spectral bands. At all wavelengths the AHI noise equivalent delta (NE Delta T) temperature is less than 0.1K at 300K and the NESR is less than .02 watts/m(2)-sr-mu m.
