AISA Hawk is extremely small for a SWIR system which means it can be installed and removed from any aircraft with relative ease. It features practically zero smile and key stone distortions and very low polarisation dependency. |
| AISA Hawk's ability to capture short wave infrared wave lenghts (1000-2400 nm) makes it an ideal tool for applications, which will benefit from data acquisition on spectral signatures characteristic to chemical compounds and man-made targets that can not be distinguished in the VNIR range. |
| Specim also offers a dual sensor system that would allow data acquisition in 400-2400 nm spectral range. This is achieved by putting AISA Hawk and Eagle sensor head side-by-side to simultaneously collect data. |
Components
| AISA Hawk a complete, pushbroom system, consisting of a hyperspectral sensor head with fiberoptic downwelling irradiance sensor (FODIS), miniature GPS/INS sensor, data acquisition unit in a rugged PC with display unit and power supply. |
 |
| The system also includes an in-flight configuration setting, which allows alterations to be made easily for each exercise, and AISA's post processing software CaliGeo . Like all of Specim's products CaliGeo has been under development so that it provides a user-friendlier interface to apply both radiometric calibration and georectification to the AISA images. CaliGeo now exists as an ENVI plug-in running under ENVI user interface and providing a seamless path from calibrated image to application processing. |
