Paper Abstract

Northrop Grumman Space Technology (NGST) completed building and testing its Long Wave Hyperspectral Imaging Spectrometer (LWHIS) at the end of 2003. The instrument is a pushbroom sensor that operates in the 8 to 12.5 micron band, providing up to 256 contiguous spectral channels with 35 nm of dispersion per pixel. LWHIS was designed to operate from both ground and airborne platforms and to meet rigorous requirements for instrument performance and calibration. Since its completion, the instrument has undergone laboratory performance validation and has taken part in a number of ground and airborne imaging experiments. These experiments have led to system upgrades which have significantly improved the instrument's performance. This paper will describe the current LWHIS system, including upgrades, data correction and calibration processes, data processing rates, and demonstrate system performance using gas release experiments conducted at ground level.
