Abstract

There is substantial research evidence which indicates that data in the short wave infrared (SWIR) spectral region will greatly improve the information content of remotely sensed data. Bands are required in the 1.55-1.75 μm and 2.08-2.35μm spectral regions for a variety of agricultural and geological investigations. It is anticipated that future Landsat sensors will use pushbroom linear array technology in order to obtain high resolution, improved sensitivity and increased system reliability. To obtain early laboratory and field data, an airborne pushbroom image system has been designed for operation in the short wave infrared spectral region. The system uses a 64-element staggered PbS array and is operated at 195°K. The instrument has been designed to operate in an aircraft and will view an 19 degree swath width with a 5.8 mrad IFOV. The spectral bandwidth of each channel is .05 μm and a NE ▵p in the order of .2% is provided. The requirements for more advanced detector arrays for use in future NASA spacecraft remote sensing instruments are also discussed.
