Abstract:

Platinum Silicide and Indium Antimonide are compared as detector materials in a space based remote sensor using the 3 to 5 micrometer wavelength band. The comparison is based on a scaled count rate involving the materials quantum efficiency, a targets reflected solar and thermal emittances, the atmospheric transmission, and the wavelength. The comparison is made using a baseline scenario and seven sensitivity analysis scenarios. The baseline scenario uses a target at 298K and a vertical line-of-sight from the target to the remote sensor in space. The atmospheric transmission is calculated using the 1962 U. S. Standard atmospheric model resident in LOWTRAN 6, with a 23 kilometer rural visibility and no cloud cover. A sensitivity analysis was performed by varying the target temperature, target reflectance, and finally the atmospheric properties.
