12 June 1995 Airborne and satellite imaging spectrometer development at TRW
Author Affiliations +
TRW has been involved in hyperspectral imaging since late 1989. The first instruments were constructed from commercially available components and were restricted in wavelength response to the visible and near IR (i.e., about 0.48 micrometers to 0.88 micrometers). They were used to take data from airborne platforms to support phenomenology studies. An instrument was then constructed to make measurements in the SWIR (i.e., out to 2.5 micrometers). It used mostly commercial components and contained some custom developments such as the foreoptics. These early instruments all recorded data using videotape recorders. A real time processor has been constructed which performs real time spectral template matching on six spectral templates. This significantly reduces operator load for systems where spectrally known targets are being sought. We are currently developing three new systems using custom components. The first is a high performance, aircraft based instrument called TRWIS III; the second, called HSI, will be the first hyperspectral imager in space, and is being developed for the NASA Small Satellite Technology Initiative; and the third is an ocean color instrument, known as the Low Resolution Camera, using the hyperspectral approach. Each of these instruments will be briefly described.
